Simple Example of JavaScript *this* Referring to Two Different Objects

Let's say we have this JavaScript object:

What will this display in the console log?

That depends on how displayThis() is called.

If we called it this way:

musician.displayThis();

this would be the musician object:

Why? Because we called displayThis() via the musician object, and the musician object's this is itself.

If we called it this way:

var outside = musician.displayThis;
outside();

this would be the Window object:

Why? Because we called displayThis() via the outside object, and the outside object's this is Window.
