awesome!!

Illegible tbh

Ahh, the 'because I can' solution lol.

But what is exactly the questions here? The " 1234 5678 " is not a valid phone number (because of superfluous spaces), so the isValidHKPhoneNumber is expected to return false. However, it contains a valid phone number somewhere inside, so the hasValidHKPhoneNumber is expected to return true. What is the problem I am missing?

The same is here on JS. No-one responded yet, really? 😵‍💫

Combine so many ternary operators in 1 line so bad, bro

It just has to fit into one line...

I don't know how this isn't #1 for best practices

wtf

This thing is a monster

I am aware, but I just added that to illustrate that at the very least nesting ternary statements is a bad idea for readability.

this isn't php..

nah this is perfect

I dont know what is going on in your head but fix it
