JavaScript is a high-level, interpreted (or just-in-time compiled) programming language that conforms to the ECMAScript specification. It is a core technology of the World Wide Web, alongside HTML and CSS, and is used by the vast majority of websites for client-side page behavior. As a multi-paradigm language, it supports event-driven, functional, and imperative programming styles.
Syntactic sugar is a term in programming language design for surface-level syntax that makes code easier to write or read without increasing a language’s expressive power. Coined by Peter J. Landin in 1964, it is typically compiled away by translating to more primitive constructs, a process often called desugaring.
