Why is javascript important

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.

JavaScript brings the website to life by adding functionality. 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 it is on the client side aka frontend , but since Node. 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 in our guide. 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 the language, such as web apps and server apps.

But now that we know some of the array of uses of this twenty five year-old language, why learn JavaScript in ? 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. It is currently used by If you want to kick things off now and get a taste, in this video our resident web developer Abhishek gives you an introduction to JavaScript. The most obvious reason for learning JavaScript is if you have hopes of becoming a web developer.

Since , WebAssembly is also supported by modern browsers. JavaScript also is compatible with other languages. You want to have a real feel of what is JavaScript doing for the web? Try turning it off in your web browsers and see the result! I still think of it as a quickie love-child of C and Self.

Yet, here we are, more than ten years later and JavaScript is more present than ever before. For answers, we need to look at the amazing ecosystem that was built on it. This update added new syntax for writing more complex applications and many other features that would define the next era of JavaScript.

Either way, this vibrant community and the rise of the web have taken JavaScript place it was never conceived to be. Server-side code was handling the major part of the logic. Modern browsers now have the capacity to make these interactive and fully-dynamic.

A particularity they share with their ancestors, though, is the abstraction of backend development. Logic is handled client-side, directly in the browser, thanks to JavaScript. Modern web trends were born from this new paradigm, like the JAMstack. I wrote a whole post on the subject that I invite you to read here. Some of the most prominent web applications around today are built using JS.

Think Facebook, Gmail, Twitter, and many more. If we use Facebook as an example, JavaScript enables status updates and most user interactivity. These tech giants actually built their own frameworks of JavaScript, and these now allow thousands of devs to build their own web apps. I also have to mention Vue here that, even if not supported by a tech powerhouse, completes the triad of important JS frameworks. Other than reducing the amount of time and efforts required for developing JS-based sites and apps, these frameworks helped shape new web experiences.

A SPA is a website that interacts with users by dynamically rewriting a page in the browser rather than loading entire new pages from a server, making them behave more like desktop applications. Yes, the primary use of JavaScript might still be for frontend web development. There were unsuccessful attempts to make JavaScript run server-side from the very beginning. Many thought it would just never become a stable backend language, until the arrival of Node.

Today, this JS runtime is a popular tool to power web servers. This means that JS developers can use Node. Scan My Site. Upgrade Your Site with the Latest Tech. We Can Help. Contact Us
