Explanation Explanation: When comparison is made using double-equals operator (==), it will check the values of variable and convert them to a common type and returns true if both are equals. So comparing number with string having the same value will return true. Examples: examples: console.log(23 == "23"); // true console.log(1 == true); // true Incorrect: not ===: This is strict or identical equality. Reference: JavaScript Triple Equals Operator vs Double Equals Operator ( === vs == )
