Question

I’ve read through a lot of code where they have if statements, i’ve noticed other languages use this to. Asp being one.
Tried googling but couldn’t find a answer for it.

What exactly does ?: stand for and when to use it.

As far as I’m aware ? is equal to if() and : being equal to }else{.

Answer 1

This is called ternary operator.

It is meant to simplify code in some cases. Consider this:

var str;

if(some_condition)
  str = 'yes';
else
  str = 'no';

This can be easily rewritten as

var str = some_condition ? 'yes' : 'no';
