Identity (===. !==) vs Equality (==, !=) operators in JavaScript

These operators behave identically to the equality operators except no type conversion is done, and the types must be the same to be considered equal.

Using the == operator (Equality)

     true == 1; //true, because 'true' is converted to 1 and then compared
     "2" == 2;  //true, because "2" is converted to 2 and then compared

Using the === operator (Identity)

     true === 1; //false
     "2" === 2;  //false

This is because the equality operator == does type coercion, meaning that the interpreter implicitly tries to convert the values before comparing.

On the other hand, the identity operator === does not do type coercion, and thus does not convert the values when comparing.
