What is the benefit of === as opposed to == in this scenario?

=== vs == in this scenario - is there a benefit and why does the teacher use === here?

the == is the equal to operator, the === is the identical to (equal and also of same type) operator. the equal == attempts to convert the type of one operand to the same type as the other, whereas the identical === does not type convert. this means that 5 == '5' will return true, but 5 === '5' will return false.

Hi James,

thanks for the reply.

Indeed, I understand it now too. If anybody else was also wondering, he actually explains this in the very next video.
