Free JavaScript

What is JavaScript?

JavaScript, commonly referred to as JS, is a scripting language that emerged 28 years ago, specifically in 1995. The language was originally created by Brendan Eich while working at Netscape. As a just-in-time and high-level compiled language, it adheres to the ECMAScript standard. JavaScript serves the purpose of enhancing functionality and interactivity within web pages. It can be employed for both front-end and back-end development.

Web browsers are equipped with a specialized JavaScript engine that is responsible for processing and executing client-side code. This technology serves a multitude of purposes, including but not limited to mobile application development, web development, creating presentations, server-side programming, and game development, among others.

Features of JavaScript

Here are several characteristics of JavaScript outlined below:

• ✅ Lightweight scripting language JavaScript is created for handling data at the client side in the browser which is why it is lightweight in nature. This language can be run on
• ✅ Dynamic typing Variables are defined on the basis of stored value in JavaScript which is called dynamic typing. If the stored value is string type then the variable type becomes string type and if the stored value is number type then the variable type becomes a number type.
• ✅ Platform independent JavaScript is a platform independent language, meaning it can be run on any operating system. The platform independent languages are written once and run anywhere.
• ✅ Interpreted Language JavaScript is an interpreted language, meaning the code is checked line by line with the help of built-in interpreter of the web browser.
• ✅ Object-oriented programming support JavaScript is an object-oriented programming language that means it uses two concepts of OOPs which are encapsulation and inheritance.
• ✅ Prototype based language JavaScript is a prototype-based scripting language which means it utilizes prototypes in place of using classes or inheritance.
• ✅ Single threaded JavaScript supports single threading which simply means it executes a single task at a time but it supports other features to implement parallel execution.
• ✅ Async processing JavaScript supports async processing which means tasks can be performed in parallel so that the processing time is reduced.
• ✅ Case sensitive JavaScript is a case sensitive language, meaning capital letters and small letters matter. If the same word is written in both small letters and capital letters then both will show a different output.
• ✅ Statements looping JavaScript supports looping which means the same piece of code can be executed multiple times which reduces time.
