JavaScript was initially created to make web pages interactive, dynamic, and alive. It was used to enhance the users’ interaction with the webpage.
Scripts can be written right in a web page’s HTML and run automatically as the page loads.
Scripts are provided and executed as plain text. They don’t need compilation to run.
JS can do multiple tasks like displaying timely content updates, interactive maps, animated 2D and 3D graphics, jukeboxes, etc. JS is an open-source and popular client-side scripting language supported by all modern browsers like Chrome, Firefox, Opera, Safari, etc.
Developers today can create pages that work across various browsers, platforms, and devices by using HTML5, CSS3 JavaScript. It is Cross-Browser Compatible.
