Third Party Libraries and Declaration Files

Introduction to third-party libraries

One of the benefits of JavaScript development is the ability to download and install a whole host of third-party libraries that have been built to accomplish a huge variety of things in JavaScript. JavaScript libraries are collections of pre-written JavaScript code that make it easier for developers to build interactive applications. A library can save developers time and effort as they don’t have to write as much code from scratch. There are many different libraries available for use, and they can be used to perform a wide variety of tasks, such as manipulating the DOM, making HTTP requests, and animating elements on a page.

The easiest way to download and install them is to use the npm program that is packaged with Node. In order to do this, we start by initializing the npm environment within our project subdirectory with the npm init command.
