The number of programming languages used in the world is massive owing to the constantly evolving software industry. In order to survive in the ever-changing world of programming, one needs to be aware of all the technologies added to the popular list.

JavaScript is one such popular guy on the list which has been able to survive in the world of programming for quite a few years. Netscape’s LiveScript was the father of JavaScript, whose main job was to help develop apps easily. JavaScript overrode LiveScript by invading the server-side and set foot on a more concrete ground in the world of programming languages. Currently, Javascript is one of the most used programming languages in the world and is dominant in many aspects ranging from web pages to mobile web apps. But why is it so popular? Here is a list of reasons gathered by dzone.

1. Inexpensive to learn

The syntax is based on simple English and any programmer can follow up quickly and easily. In contrast to some popular languages, JavaScript does not require special compilers, a simple text editor and a web browser is all it needs.

2. Simple implementation

Development teams find it fascinating to be able to use a single language to face the front end and the back end.

3. Extended functionality

There are third party add-ons available that allow developers to write code snippets which can be implemented easily.

4. Client-side processing

The code is actually executed on the user’s processor and not on a remote web server which saves the bandwidth and additional load on the server. Furthermore, browsers have their own in-built JavaScript so the user is not required to download extra tools to experience JavaScript.

5. Quick feedback for the client

Gone are the days where the user has to fill in an entire form again because of a single typo made on the previously submitted one. JavaScript validates each field right after entering it.
