var str1 = "Javascript";
var str2 = "Javascript";

console.log(,str2)); // true

var num1 = 100.25;
var num2 = 100.25;
console.log(,num2)); // true

console.log(,null)); // true

var arr1 = [];
var arr2 = [];
console.log(,arr2)); // false
var arr3 = arr1;
console.log(,arr3)); // false

var obj1 = {};
var obj2 = {};
console.log(,obj2)); // false
var obj3 = obj1;
console.log(,obj3)); // true
