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's JON (Javascript Object Notation) for creating a new empty object. Almost equal in idea to how you'd normally do Object x = new Object() in java, minus the initialization part...
