JavaScript
With about 12.4 million worldwide users, JavaScript is one of the world's most popular programming languages. Because of its versatility and front-end and back-end applications, Javascript is frequently used to develop web browsers, embedded hardware controls, games, and software systems.
Often, developers use this text-based language to add interactive elements to web pages, such as search boxes, zoom features, or drop-down menus. Developers may access JavaScript code libraries and draw from pre-written frameworks while creating web pages or applications. Some highly influential mobile applications, including Uber and PayPal, were built from JavaScript's front-end frameworks.
