What Is JavaScript?
JavaScript is a dynamic computer programming language. It is lightweight and most commonly used as a part of web pages, whose implementations allow a client-side script to interact with the user and make dynamic pages. It is an interpreted programming language with object-oriented capabilities.
Why Do We Use?
JavaScript is most commonly used as a client-side scripting language. This means that JavaScript code is written into an HTML page. When a user requests an HTML page with JavaScript in it, the script is sent to the browser and it's up to the browser to do something with it.
