JavaScript is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS. It is a scripting language that enables you to create dynamically updating content, control multimedia, animate images, and pretty much everything else. JavaScript is a high-level, often just-in-time compiled language that conforms to the ECMAScript standard. It has dynamic typing, prototype-based object-orientation, and first-class functions. It is multi-paradigm, supporting event-driven, functional, and imperative programming styles. It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM) .
JavaScript is used to create dynamic and interactive content on web applications and browsers. It is the dominant client-side scripting language of the Web, with 98% of all websites using it for this purpose. JavaScript can update and change both HTML and CSS, calculate, manipulate and validate data, and create elements for improving site visitors’ interaction with web pages, such as dropdown menus, animated graphics, and dynamic background colors.
JavaScript is a lightweight, cross-platform, single-threaded, and interpreted compiled programming language. It is also known as the scripting language for webpages. It is well-known for the development of web pages, and many non-browser environments also use it. JavaScript is a weakly typed language (dynamically typed). JavaScript can be used for Client-side developments as well as Server-side developments. JavaScript is both an imperative and declarative type of language. JavaScript contains a standard library of objects, like Array, Date, and Math, and a core set of language elements like operators, control structures, and statements.
JavaScript is capable of so much more than just creating dynamic web pages. It can be used to create great experiences for users, and it is the most popular language on earth according to a recent survey conducted by Stack Overflow.
