Benefits of JavaScript programming

Simplicity

The JavaScript language is relatively straight-forward and easy to learn. Experienced developers can pick up different frameworks and syntaxes quite easily.

Popularity

JavaScript has dominated frontend development for decades and is now growing in popularity in fullstack web development, without the need for a backend language.

Versatility

It is possible to develop an entire application from front to back using only JavaScript. There are many ways to use JS for full-stack development.

Speed

Client-side JavaScript is very fast because it can be run immediately within the client-side browser, unhindered by network calls to a backend server.
