Ew no.
Abusing language features like this (boolean expression short circuit) just makes it harder for other people to come and maintain your code.
The function does have opportunity for improvement by checking one thing at a time. This flattens the ifs and changes them into proper sentry clauses. It also opens the door to encapsulating their logic and refactoring this function into a proper validator that can return all the reasons a user is invalid.
Good code is not "elegant" code. It's code that is simple and unsurprising and can be easily understood by a hungover fresh graduate new hire.
I mean, boolean short circuit is a super idiomatic pattern in Javascript
I think that’s very team/project dependent. I’ve seen it done before indeed, but I’ve never been on a team where it was considered idiomatic.
That makes sense.
Because on JS the goal is to shave bytes to save money on data transfer rates
It's not that deep. It looks nice, and is easy to understand.
