WHAT IS JAVASCRIPT?
JavaScript, often abbreviated as JS, is a programming language that conforms to the ECMAScript specification.
JavaScript is high-level, often just-in-time compiled, and multi-paradigm. It has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions. Educative Logo
WHAT IS THE USE OF JS?
JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive.
Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive elements that engage a user.
As a multi-paradigm language, JavaScript supports 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). However, ECMAScript itself does not include any input/output (I/O), such as networking, storage, or graphics facilities, as the host environment (usually a web browser) provides those APIs.
