Hi! An object literal is simply a set of name and value pairs wrapped in curly braces. To expand on the example you're looking at I made this object literal.

var player = {
    name: 'Jennifer',
    score: 0,
    highScore: 200,
    level: 2,
    isAlive: true
}

The name is the word before the colon and the value comes after the colon and can really be any data type at all. Hope that helps!

An object lateral is basically an object. An object is representation of things in the world.

player will have properties of the following. name, score, highScore, level, and boolean.

Object laterals are used to store data and prevent things from colliding overwritten. Also known as a namespace.

'use strict';
console.log(player.name); // Jennifer

Will print.
