Q. Can you explain the difference between == and === in JavaScript?
In JavaScript, == checks for value equality, while === checks for both value and type equality.
== (loose equality) converts types if they are different: 5 == '5' is true.
=== (strict equality) does not convert types: 5 === '5' is false.
Use === to avoid unexpected type coercion and ensure both value and type match.
Example: null == undefined is true, but null === undefined is false.
