About JavaScript Programming

Prototype-based Object-oriented - JavaScript is an object-oriented programming language. It used prototypes instead of classes. Objects are used to represent the real-world entity in the program.

Interpreted Language - JavaScript is an interpreted programming language. It uses a just-in-time compilation technique at run-time.

Event-Based Programming - JavaScript allows us to write codes that are executed differently under different events.

Platform Independence - JavaScript codes are run on browsers. So irrespective of the machine, if the browser supports JavaScript, codes can run.

Why Learn JavaScript?

  • JavaScript is used on both the client-side and the server-side. On the client-side, the code is run and displayed by the browser. On the server-side, Node.js is used.
  • JavaScript is a platform-independent language. Any browser supporting JavaScript can run the code irrespective of the operating system
  • JavaScript uses the just-in-time compilation technique. Since the compilation is handled at run time, JavaScript is considered an interpreted language.
  • JavaScript is a dynamically typed language. That is, a variable containing a number may be reassigned to a string.
