So the best I can do is to guess usage scenarios. 1) Fast and limited. Works when you have simple JSON-style objects without methods and DOM nodes inside: JSON.stringify(obj1) === JSON.stringify(obj2) The ORDER … Read more
You have = the assignment operator, == the ‘equal’ comparison operator and === the ‘identical’ comparison operator. $a = $b Assign Sets $a to be equal to $b. $a == $b Equal TRUE if $a is equal to $b. $a === $b Identical TRUE if $a is equal to $b, and they are of the … Read more
