Dropin replacement for '===' that supports deep objects compare. JavaScript object deep comparison.Comparing x === y, where x and y are values, return true or false. Comparing x === y, where x and y are objects, returns true if x and y refer to the same object. Otherwise, returns false even if the objects appear identical.Here is a solution to c…

1_primitive_comparison.js

//Primitive Type Comparison
var a = 1;
var b = 1;
var c = a;

console.log(a == b);  //true
console.log(a === b); //true
console.log(a == c);  //true
console.log(a === c); //true

2_obeject_comparison.js

//Object comparison
var a = { blah: 1 };
var b = { blah: 1 };
var c = a;

console.log(a == b);    //false
console.log(a === b);   //false
console.log(a == c);	  //true
console.log(a === c);   //true

compare.js

//How To Compare Object Values
var a = { blah: 1 };
var b = { blah: 1 };
var c = a;
var d = { blah: 2 };
var e = 5;
var f = 5;
var g = 6;

const Compare = function (obj1, obj2) {
    	// if they are not of the same type, don't bother
	if(typeof (obj1) !== typeof (obj2)) return false;
	
	// support non object types as well
    	if(typeof (obj1) != 'object')
        	return obj1 == obj2
	
	//Loop through properties in object 1
	for (var p in obj1) {
		//Check property exists on both objects
		if (obj1.hasOwnProperty(p) !== obj2.hasOwnProperty(p)) return false;
 
		switch (typeof (obj1[p])) {
			//Deep compare objects
			case 'object':
				if (!Object.compare(obj1[p], obj2[p])) return false;
				break;
			//Compare function code
			case 'function':
				if (typeof (obj2[p]) == 'undefined' || (p != 'compare' && obj1[p].toString() != obj2[p].toString())) return false;
				break;
			//Compare values
			default:
				if (obj1[p] != obj2[p]) return false;
		}
	}
 
	//Check object 2 for any extra properties
	for (var p in obj2) {
		if (typeof (obj1[p]) == 'undefined') return false;
	}
	return true;
};

console.log(Compare(a, b));  //true
console.log(Compare(a, c));  //true
console.log(Compare(a, d));  //false

console.log(Compare(e, f));  //true
console.log(Compare(e, g));  //false

Fails with the below example:

  var oldObj = {
