Get the object length in angularjs is undefined

Question

How can I get the object length ?

In console my object looks like this:

Object {
 2: true,
 3: true,
 4: true
}

.length w

Answer 1

var keys = Object.keys(objInstance);
var len = keys.length;

Where len is your "length."

There may be circumstances I haven't thought of where this doesn't work, but it should do what you need, given your example.
