Q3. Difference between == and ===
Ans. 
The difference between == and === is that == checks for equality after type coercion, while === checks for equality without type coercion.
• == is a loose equality operator that performs type coercion before comparing two values.

• === is a strict equality operator that does not perform type coercion before comparing two values.

• Example: 1 == '1' will return true, but 1 === '1' will return false.
