Identity Operator (===) vs. Equality Operator (==)
Be sure to know the difference between the identify operator (===) and equality operator (==) in javascript! The
    == operator will do type conversion prior to comparing values whereas the === operator will not do any type
    conversion before comparing.
                
                    
console.log(0 == '0');
                        // true
                        console.log(0 === '0');
                        // false
