JavaScript(JS) Introduction

JavaScript is a programming language that is primarily used to create interactive and dynamic web pages. It is a high-level, interpreted language, which means that it does not need to be compiled before it can be run. JavaScript is supported by all modern web browsers and is often used in conjunction with HTML and CSS to create dynamic and interactive user interfaces.

JavaScript was originally developed by Brendan Eich in 1995 while he was working at Netscape Communications Corporation. Initially, it was intended to be a scripting language for web browsers, but over the years it has evolved to become a general-purpose programming language that can be used for a wide range of applications.

Some common uses of JavaScript include:

  • Creating dynamic web pages that respond to user interactions
  • Validating forms and handling user input
  • Adding animations and effects to web pages
  • Building web applications, including games and other interactive experiences
  • Developing server-side applications using Node.js

JavaScript is a versatile language that can be used for a wide range of applications, from simple scripts to complex web applications. It has a large and active community of developers who contribute to open-source libraries and frameworks, making it easy to find solutions to common problems and to share knowledge with other developers.
