- ==: compares the value of the variables
- ===: compares the type and value of the variables
For example, 5 === "5" will return a false result. Even though the value of both variables is the same, their type is not; one of them is a String ("5"), and the other one is an Integer (5).
On the other hand, 5 == "5" will return a true result. Both variables have the same value; therefore, the result will be true.
