sanusanth / Javascript Basic ProgramWhat is JavaScript and what does it do? Before you start learning something new, it’s important to understand exactly what it is and what it does. This is especially useful when it comes to mastering a new programming language. In simple terms, JavaScript is a programming language used to make websites interactive. If you think about the basic makeup of a website, you have HTML, which describes and defines the basic content and structure of the website, then you have CSS, which tells the browser how this HTML content should be displayed—determining things like color and font. With just HTML and CSS, you have a website that looks good but doesn’t actually do much. JavaScript brings the website to life by adding functionality. JavaScript is responsible for elements that the user can interact with, such as drop-down menus, modal windows, and contact forms. It is also used to create things like animations, video players, and interactive maps. Nowadays, JavaScript is an all-purpose programming language—meaning it runs across the entire software stack. The most popular application of JavaScript is on the client side (aka frontend), but since Node.js came on the scene, many people run JavaScript on the server side (aka backend) as well. When used on the client side, JavaScript code is read, interpreted, and executed in the user’s web browser. When used on the server side, it is run on a remote computer. You can learn more about the difference between frontend and backend programming here. JavaScript isn’t only used to create websites. It can also be used to build browser-based games and, with the help of certain frameworks, mobile apps for different operating systems. The creation of new libraries and frameworks is also making it possible to build backend programs with JavaScript, such as web apps and server apps. Is it still worth learning JavaScript in 2021? The world of web development is constantly moving. With so many new tools popping up all the time, it can be extremely difficult to know where you should focus your efforts. As an aspiring developer, you’ll want to make sure that what you’re learning is still relevant in today’s industry. If you’re having doubts about JavaScript, it’s important to know that, since its creation in 1995, JavaScript is pretty much everywhere on the web—and that’s not likely to change any time soon. According to the 2020 StackOverflow developer survey, JavaScript is the most commonly used programming language for the eighth year in a row. It is currently used by 94.5% of all websites and, despite originally being designed as a client-side language, JavaScript has now made its way to the server-side of websites (thanks to Node.js), mobile devices (thanks to React Native and Ionic) and desktop (courtesy of Electron). As long as people are interacting with the web, you can assume that JavaScript is highly relevant—there’s no doubt that this is a language worth knowing! With that in mind, let’s look at some of the key benefits of becoming a JavaScript expert. Why learn JavaScript? The most obvious reason for learning JavaScript is if you have hopes of becoming a web developer. Even if you haven’t got your heart set on a tech career, being proficient in JavaScript will enable you to build websites from scratch—a pretty useful skill to have in today’s job market! If you do want to become a web developer, here are some of the main reasons why you should learn JavaScript: JavaScript experts are versatile JavaScript is an extremely versatile language. Once you’ve mastered it, the possibilities are endless: you can code on the client-side (frontend) using Angular and on the server-side (backend) using Node.js. You can also develop web, mobile, and desktop apps using React, React Native, and Electron, and you can even get involved in machine learning. If you want to become a frontend developer, JavaScript is a prerequisite. However, that’s not the only career path open to you as a JavaScript expert. Mastering this key programming language could see you go on to work in full-stack development, games development, information security software engineering, machine learning, and artificial intelligence—to name just a few! Ultimately, if you want any kind of development or engineering career, proficiency in JavaScript is a must. JavaScript experts are in-demand (and well-paid) JavaScript is the most popular programming language in the world, so it’s no wonder that JavaScript is one of the most sought-after skills in the web development industry today. According to the Devskiller IT Skills and Hiring Report 2020, 72% of companies are looking to hire JavaScript experts. Enter the search term “JavaScript” on job site Indeed and you’ll find over 40,000 jobs requiring this skill (in the US). Run the same search on LinkedIn and the results are in excess of 125,000. At the same time, the global demand for JavaScript seems to outweigh the expertise available on the market. According to this 2018 HackerRank report, 48% of employers worldwide need developers with JavaScript skills, while only 42% of student developers claim to be proficient in JavaScript. And, in their most recent report for 2020, HackerRank once again reports that JavaScript is the most popular language that hiring mangers look for in a web developer candidate. Not only are JavaScript experts in demand—they are also well-paid. In the United States, JavaScript developers earn an average yearly salary of $111,953 per year. We’ve covered this topic in more detail in our JavaScript salary guide, but as you can see, learning JavaScript can really boost your earning potential as a developer. JavaScript is beginner-friendly Compared to many other programming languages, JavaScript offers one of the more beginner-friendly entry points into the world of coding. The great thing about JavaScript is that it comes installed on every modern web browser—there’s no need to set up any kind of development environment, which means you can start coding with JavaScript right away! Another advantage of learning JavaScript as your first programming language is that you get instant feedback; with a minimal amount of JavaScript code, you’ll immediately see visible results. There’s also a huge JavaScript community on sites like Stack Overflow, so you’ll find plenty of support as you learn. Not only is JavaScript beginner-friendly; it will also set you up with some extremely valuable transferable skills. JavaScript supports object-oriented, functional, and imperative styles of programming—skills which can be transferred to any new language you might learn later on, such as Python, Java, or C++. JavaScript provides a crucial introduction to key principles and practices that you’ll take with you throughout your career as a developer. Should you learn plain JavaScript first or can you skip to frameworks and libraries? When deciding whether or not to learn JavaScript, what you’re really asking is whether or not you should learn “vanilla” JavaScript. Vanilla JavaScript just means plain JavaScript without any libraries or frameworks. Let’s explore what this means in more detail now. What is meant by vanilla JavaScript, libraries, and frameworks? If you research the term “vanilla JavaScript”, you might run into some confusion; however, all you need to know is that vanilla JavaScript is used to refer to native, standards-based, non-extended JavaScript. There is no difference between vanilla JavaScript and JavaScript—it’s just there to emphasize the usage of plain JavaScript without the use of libraries and frameworks. So what are libraries and frameworks? JavaScript libraries and frameworks both contain sets of prewritten, ready-to-use JavaScript code—but they’re not the same thing. You can think of a framework as your blueprint for building a website: it gives you a structure to work from, and contains ready-made components and tools that help you to build certain elements much quicker than if you were to code them from scratch. Some popular JavaScript frameworks include Angular, React, Vue, and Node.js. Frameworks also contain libraries. Libraries are smaller than frameworks, and tend to be used for more specific cases. A JavaScript library contains sets of JavaScript code which can be called upon to implement certain functions and features. Let’s imagine you want to code a particular element into your website. You could write, say, ten lines of JavaScript from scratch—or you could take the condensed, ready-made version from your chosen JavaScript library. Some examples of JavaScript libraries include jQuery, Lodash, and Underscore. The easiest way to understand how frameworks and libraries work together is to imagine you are building a house. The framework provides the foundation and the structure, while the library enables you to add in ready-made components (like furniture) rather than building your own from scratch. You can learn more about the relationship between languages and libraries in this post explaining the main differences between JavaScript and jQuery. For now, let’s go back to our original question: How important is it to learn vanilla JavaScript? Should you learn vanilla JavaScript first? When it comes to learning JavaScript, it can be tempting to skip ahead to those time-saving frameworks and libraries we just talked about—and many developers do. However, there are many compelling arguments for learning plain JavaScript first. While JavaScript frameworks may help you get the job done quicker, there’s only so far you can go if you don’t understand the core concepts behind these frameworks. Frontend developer Abhishek Nagekar describes how not learning vanilla JavaScript came back to bite him when he started learning the JavaScript frameworks Node and Express: “As I went to write more and more code in Node and Express, I began to get stuck at even the tiniest problems. Suddenly, I was surrounded with words like callbacks, closures, event loop and prototype. It felt like I got a reintroduction to JavaScript, but this time, it was not a toddler playing in its cradle, it was something of a mysterious monster, challenging me on every other step for not having taken it seriously.” The above Tweet references a long-running joke within the developer community, and although it dates way back to 2015, it’s still highly relevant today. If you want to become a developer who can innovate, not just execute, you need to understand the underlying principles of the web—not just the shortcuts. This means learning vanilla JavaScript before you move on to frameworks. In fact, understanding plain JavaScript will help you later on when it comes to deciding whether to use a framework for a certain project, and if so, which framework to use. Why Study JavaScript? JavaScript is one of the 3 languages all web developers must learn: 1. HTML to define the content of web pages 2. CSS to specify the layout of web pages 3. JavaScript to program the behavior of web pages Learning Speed In this tutorial, the learning speed is your choice. Everything is up to you. If you are struggling, take a break, or re-read the material. Always make sure you understand all the "Try-it-Yourself" examples. The only way to become a clever programmer is to: Practice. Practice. Practice. Code. Code. Code ! Commonly Asked Questions How do I get JavaScript? Where can I download JavaScript? Is JavaScript Free? You don't have to get or download JavaScript. JavaScript is already running in your browser on your computer, on your tablet, and on your smart-phone. JavaScript is free to use for everyone.

Tinkprocodes / Fca UnofficialThis repo is a fork from main repo and will usually have new features bundled faster than main repo (and maybe bundle some bugs, too). # Unofficial Facebook Chat API <img alt="version" src="https://img.shields.io/github/package-json/v/ProCoderMew/fca-unofficial?label=github&style=flat-square"> Facebook now has an official API for chat bots [here](https://developers.facebook.com/docs/messenger-platform). This API is the only way to automate chat functionalities on a user account. We do this by emulating the browser. This means doing the exact same GET/POST requests and tricking Facebook into thinking we're accessing the website normally. Because we're doing it this way, this API won't work with an auth token but requires the credentials of a Facebook account. _Disclaimer_: We are not responsible if your account gets banned for spammy activities such as sending lots of messages to people you don't know, sending messages very quickly, sending spammy looking URLs, logging in and out very quickly... Be responsible Facebook citizens. See [below](#projects-using-this-api) for projects using this API. ## Install If you just want to use fca-unofficial, you should use this command: ```bash npm install procodermew/fca-unofficial ``` It will download `fca-unofficial` from NPM repositories ## Testing your bots If you want to test your bots without creating another account on Facebook, you can use [Facebook Whitehat Accounts](https://www.facebook.com/whitehat/accounts/). ## Example Usage ```javascript const login = require("fca-unofficial"); // Create simple echo bot login({email: "FB_EMAIL", password: "FB_PASSWORD"}, (err, api) => { if(err) return console.error(err); api.listen((err, message) => { api.sendMessage(message.body, message.threadID); }); }); ``` Result: <img width="517" alt="screen shot 2016-11-04 at 14 36 00" src="https://cloud.githubusercontent.com/assets/4534692/20023545/f8c24130-a29d-11e6-9ef7-47568bdbc1f2.png"> ## Documentation You can see it [here](DOCS.md). ## Main Functionality ### Sending a message #### api.sendMessage(message, threadID[, callback][, messageID]) Various types of message can be sent: * *Regular:* set field `body` to the desired message as a string. * *Sticker:* set a field `sticker` to the desired sticker ID. * *File or image:* Set field `attachment` to a readable stream or an array of readable streams. * *URL:* set a field `url` to the desired URL. * *Emoji:* set field `emoji` to the desired emoji as a string and set field `emojiSize` with size of the emoji (`small`, `medium`, `large`) Note that a message can only be a regular message (which can be empty) and optionally one of the following: a sticker, an attachment or a url. __Tip__: to find your own ID, you can look inside the cookies. The `userID` is under the name `c_user`. __Example (Basic Message)__ ```js const login = require("fca-unofficial"); login({email: "FB_EMAIL", password: "FB_PASSWORD"}, (err, api) => { if(err) return console.error(err); var yourID = "000000000000000"; var msg = "Hey!"; api.sendMessage(msg, yourID); }); ``` __Example (File upload)__ ```js const login = require("fca-unofficial"); login({email: "FB_EMAIL", password: "FB_PASSWORD"}, (err, api) => { if(err) return console.error(err); // Note this example uploads an image called image.jpg var yourID = "000000000000000"; var msg = { body: "Hey!", attachment: fs.createReadStream(__dirname + '/image.jpg') } api.sendMessage(msg, yourID); }); ``` ------------------------------------ ### Saving session. To avoid logging in every time you should save AppState (cookies etc.) to a file, then you can use it without having password in your scripts. __Example__ ```js const fs = require("fs"); const login = require("fca-unofficial"); var credentials = {email: "FB_EMAIL", password: "FB_PASSWORD"}; login(credentials, (err, api) => { if(err) return console.error(err); fs.writeFileSync('appstate.json', JSON.stringify(api.getAppState())); }); ``` Alternative: Use [c3c-fbstate](https://github.com/c3cbot/c3c-fbstate) to get fbstate.json (appstate.json) ------------------------------------ ### Listening to a chat #### api.listen(callback) Listen watches for messages sent in a chat. By default this won't receive events (joining/leaving a chat, title change etc…) but it can be activated with `api.setOptions({listenEvents: true})`. This will by default ignore messages sent by the current account, you can enable listening to your own messages with `api.setOptions({selfListen: true})`. __Example__ ```js const fs = require("fs"); const login = require("fca-unofficial"); // Simple echo bot. It will repeat everything that you say. // Will stop when you say '/stop' login({appState: JSON.parse(fs.readFileSync('appstate.json', 'utf8'))}, (err, api) => { if(err) return console.error(err); api.setOptions({listenEvents: true}); var stopListening = api.listenMqtt((err, event) => { if(err) return console.error(err); api.markAsRead(event.threadID, (err) => { if(err) console.error(err); }); switch(event.type) { case "message": if(event.body === '/stop') { api.sendMessage("Goodbye…", event.threadID); return stopListening(); } api.sendMessage("TEST BOT: " + event.body, event.threadID); break; case "event": console.log(event); break; } }); }); ``` ## FAQS 1. How do I run tests? > For tests, create a `test-config.json` file that resembles `example-config.json` and put it in the `test` directory. From the root >directory, run `npm test`. 2. Why doesn't `sendMessage` always work when I'm logged in as a page? > Pages can't start conversations with users directly; this is to prevent pages from spamming users. 3. What do I do when `login` doesn't work? > First check that you can login to Facebook using the website. If login approvals are enabled, you might be logging in incorrectly. For how to handle login approvals, read our docs on [`login`](DOCS.md#login). 4. How can I avoid logging in every time? Can I log into a previous session? > We support caching everything relevant for you to bypass login. `api.getAppState()` returns an object that you can save and pass into login as `{appState: mySavedAppState}` instead of the credentials object. If this fails, your session has expired. 5. Do you support sending messages as a page? > Yes, set the pageID option on login (this doesn't work if you set it using api.setOptions, it affects the login process). > ```js > login(credentials, {pageID: "000000000000000"}, (err, api) => { … } > ``` 6. I'm getting some crazy weird syntax error like `SyntaxError: Unexpected token [`!!! > Please try to update your version of node.js before submitting an issue of this nature. We like to use new language features. 7. I don't want all of these logging messages! > You can use `api.setOptions` to silence the logging. You get the `api` object from `login` (see example above). Do > ```js > api.setOptions({ > logLevel: "silent" > }); > ``` <a name="projects-using-this-api"></a> ## Projects using this API: - [c3c](https://github.com/lequanglam/c3c) - A bot that can be customizable using plugins.
