Why would you use === instead of ==?


If you would want to check for a certain type, like an integer or boolean, the === will do that exactly like one would expect from a strongly typed language, while == would convert the data temporarily 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 you want to avoid using == as this would also take into account 0/1 or other similar representation.
