Difference between “ == “ and “ === “ operators.

Answer»

Both are comparison operators. The difference between both the operators is that “==” is used to compare values whereas, “ === “ is used to compare both values and types.

Example:

var x = 2;
var y = "2";
(x == y) // Returns true since the value of both x and y is the same
(x === y) // Returns false since the typeof x is "number" and typeof y is "string"
