JS return and if.

Question

Okay in this core I’m trying to avoid if statements by using return.

f(x){
return if (x > 5)
}

f(4){do this) // false
f(9){do that) // true

Instead of

if (4 > 5){ do this)
if (9 > 5){do that)
if (66 > 5){blabla).

I’m trying to simply / make the code shorter by getting rid of repeated ifs. But I think I’m way off on what.
So what would be the correct way of using the return and if statement to make it shorter...?.
