    I usually ask this at interviews. So many 'senior' developers that don't know the difference

    == will return true if you are comparing 1 to "1", === will not

    One is scary, the other is sane.

    @kaqqao I guess the big issue is that we live in a world where this is a reasonable question, which would imply that people fire away their applications like tommy guns without actually knowing shit.

    == equals
    === very equals

    @DLMousey and so `===` is faster and cleaner because it won't cast any of the operands before comparing.

    ..just wanted to add that.😪
