Question

!== operator in js. How to rightly use?

Answer 1

You can use it when you need both values to be equal and of the same type. This is because the inequality operator ( != ) Does not verify the type of both values to be compared.

Example:

The expression 3! = '3' gives a false result. Since both values are equal, although they are of different types.

The expression 3! == '3' gives true as result. Since both values are equal, but are of different types
