Meaning of '{ }' in javascript

Question

What does assigning a variable to {}, mean? Is that initializing it to a function? I have code in a javascript file that says this

GLGE.Wavefront =          


        

Answer 1

It does create an empty object.

var myObj = {};

Within an object you can define key/value pairs, e.g.:

myObj.color = 'red';

A value can be a function, too:

myObj.getColor = function() { return this.color };
