I find it helps when you use short-circuiting. The returns are the first thing you see, making it more obvious what is going on. myfn = (arg) -> return 1

I find it helps when you use short-circuiting. The returns are the first thing you see, making it more obvious what is going on.
myfn = (arg) ->
return 1 if arg is "one"
return 2 if arg is "two"
return arg.toInt()
This is obviously a little contrived with such a short method, but helps when you have stuff to do between conditional returns.
- epidemian 14y agoYeah. The example is not very good, as it would probably be better to write as switch expression. But on a complex function, returning early can avoid the need to retain a lot of context in your head while reading that code. I find it especially helpful for returning/throwing on error conditions or breaking out of recursion.
