usage: require module/path v1.2.3syntax

The "require" function is used in Node.js to load modules. The syntax is:

const myModule = require('module/path');

Here, "myModule" is a variable that refers to the module loaded from the specified path. The version number (v1.2.3) is not typically included in the path, but can be specified if the module has multiple versions installed.

For example, to load the "lodash" module version 4.17.11, the syntax would be:

const _ = require('lodash@4.17.11');
