Collection in JavaScript

JavaScript collections refer to data structures in the JavaScript programming language that are used to store and manipulate collections of values or objects. These collections provide various ways to organize and access data efficiently. There are several built-in collection types in JavaScript, and developers can also create custom collections as needed.

In JavaScript, collections like arrays, objects, sets, and maps are built-in language features. They are part of the core JavaScript language and do not require any external extensions or libraries to use. JavaScript provides these data structures as fundamental constructs for working with and organizing data within your programs.
