npm modules import in JavaScript
You can include not only your own modules,
but also modules installed via npm. At
the same time, for your modules, you
need to specify ./ before,
but for npm modules, you don’t need it.
Let's look at an example. We will install the underscore library:
npm install underscore
And include it:
import _ from 'underscore';
Let's use some functions of the imorted library:
import _ from 'underscore';
let arr = [1, 2, 3, 4, 5]
let res = _.first(arr) + _.last(arr);
console.log(res);
You can import not all functions, but only the necessary ones:
import {first, last} from 'underscore';
let arr = [1, 2, 3, 4, 5]
let res = first(arr) + last(arr);
console.log(res);
Install the lodash library. Include it to your project and use several methods from this library.
