Extract & Copy Properties

Object Destructuring

A way to assign variables from object properties.

Define an object of variables, and the destructuring syntax will pull the properties at the matching keys out and assign them to the variables.

let movies = {
	disney: 'Moana',
	pixar: 'Up',
	dreamworks: 'How to Train Your Dragon',
	nickelodeon: 'Wonder Park'
};

let {disney, pixar, dreamworks, nickelodeon} = movies;

// logs "Up"
console.log(pixar);

You can also rename a variable to something different than its key in the object. In your object variable, add a colon (:) and the new variable name you’d like to use.

let {disney, pixar, dreamworks, nickelodeon: nick} = movies;

// logs "Wonder Park"
console.log(nick);
