Is JavaScript the Future of Programming?

JavaScript is the programming language that makes a website synergistic. Slideshows and advertising pop-ups are examples of JavaScript work. JavaScript was the frosting on the cake, only responsible for user experience. When you use JavaScript with a framework called Node.js, you can now actually use JavaScript as a server-side language.

Why JavaScript is Widely Used?

JavaScript is the only client-side scripting language. Therefore, it's being used on nearly every website you see on the web. If JavaScript Runs in a browser, you don't need to download software to use it. All you need is a text editor (such as TextWrangler or TextEdit) and a browser. Despite its utility, programmers don't consider JavaScript the most refined of languages — it looks messy. CoffeeScript is an attempt to change this — it makes JavaScript look more like Ruby or Python by getting rid of curly braces and semicolons and adding white space and indents. These changes make code easier to read, whether you're returning to old code and trying to remember what it does, or working on a project with another programmer.

What JavaScript Can Do?

JavaScript can be used to build an entire site if used with Node.js and MongoDB (a database). Node.js is asynchronous, which makes it highly scalable and a great fit for all the big data out there. JavaScript is now one of the preferred ways of developing applications for Windows 8's new UI. It's the top language used on Github. Lots of sites are built with Node, including Klout, Storify and Yammer. Being able to use the same language on the front end and the back end makes life easier for development teams. JavaScript is responsible for animations like pop-up windows and with AJAX, those websites that reveal new data without a page refresh. AJAX stands for Asynchronous JavaScript And Xml, it can't be used apart from JavaScript.

Will the future be written entirely in JavaScript?

HTML5 was said to be the end of Flash, but if HTML5 is the organizational tool, it's JavaScript that's taking the place of the Flash element. Those videos or other visuals that used to be served in a plugin are now served with JavaScript, which runs in your browser, so you don't have to download a third-party plugin to see it.
