How to use jаvascript libraries in jаvascript code?

When running in a browser, your source webpage should load the. js file containing the library, e. g.,:

In a stand-alone environment, like node. js, you use the require () statement:

const crypto = require ('crypto');

To load the required libraries, you use the package manager npm:

npm install crypto

This will create a local copy of the library.
