How to test if two objects are the same with JavaScript?

Question

I need a function:

function isSame(a, b){
} 

In which, if a and b are the same, it returns true.
, I tried return a === b, b

Answer 1

You could embed Underscore.js and use _.isEqual(obj1, obj2). The function works for arbitrary objects and uses whatever is the most efficient way to test the given objects for equality.
