What are ES6 features?

Answer out loud or in your head first, then compare.

Answer

The most important ones:

let
const
arrow functions
template literals
destructuring
spread
rest
classes
Promises
modules
Map
Set
default parameters
for...of

Destructuring example:

JavaScript

const user = {
  name: "Tom",
  age: 30
};

const { name, age } = user;

Spread:

JavaScript

const updatedUser = {
  ...user,
  age: 31
};

Template literals:

JavaScript

const message = `Hello ${name}`;

How did it go? Be honest — “Not yet” puts the question on your review list.
