What are JS Libraries (Script or JavaScript) ?

Libraries (Script or JavaScript) – a file that contains a collection of functions which accomplish some useful task for your webpage. A JavaScript library or JavaScript script is a collection of pre-written code that developers can use to perform common tasks, making development faster and more efficient. When it comes to script libraries, particularly JavaScript libraries, these are collections of JavaScript code that provide reusable functions and features, which can be included in web projects to add functionality without having to write the code from scratch.For example, a JavaScript library might include functions for handling animations, making HTTP requests, manipulating the Document Object Model (DOM), or creating user interface components. Popular JavaScript libraries include jQuery, Lodash, and D3.js. By using these libraries, developers can streamline their workflow and ensure their code is more reliable and easier to maintain.
