===: Yeah, I just picked up this habit, as it is usually the safer option, especially when processing external/user input.
return: JS is one of the langs without implicit returns. Nevertheless in the middle of a function we need to be explicit anyway, since more code follows afterwards. If implicit returns were supported you could use an else block to avoid a keyword, but also not worth the effort.
Yeah I was hoping es6 is closer to functional than this. The only way to get an implicit return from the last expression is a lambda function without brackets (containing a single expression).
One fix needed:
needs to be

Oh, shoot! Thank you. I thought that could implicitly return.
