If you would want to check for a certain type, like an integer or boolean, the === will do that specifically like one would assume from a strongly typed language, while == would convert the data tentatively and try to match both operand’s types.
The identity operator (===) also performs better as a result of not having to deal with type conversion.
Especially when checking variables for true/false, one should avoid practicing == as this would also take into account 0/1 or other similar representation.
