Differences between Import and require?

Question

JavaScript

Good afternoon everyone, I wanted to know what are the differences between import and required in javascript. For example, we have two connections

import './components';
require('./helpers');

What is their difference? I would be grateful for a detailed answer or a link to a resource where you can read

Answer 1

Answer 2

The import is fresher and a bit more convenient when getting variables from the export.
Basically, the difference is in support - it won't work everywhere without Babel.
