What's the difference between import from 'events' vs. import {EventEmitter} from 'events'?

Question

Seems both can work. the two e1 listed below are both EventEmitters and can be used that way.

import { EventEmitter } from "events";
let e1 = new EventEmitter();

import events from "events";
let e1 = new events();

I googled and found no answers. I also researched node docs and found the the differences starts from node 4.x (at 0.12.x, it was still import from Events.EventEmitter).

Could anyone help explain what's the difference here?

When you use curly braces { } while importing from a module, You are directly importing specific export from a module called named exports and not the whole module.

Modules can have a default export which can be imported without using the curly braces. import MyModule from './MyModule . This default export may give you access to other exports of the module depending how the module handles it's exports.
