Javascript shorthand if-else and returning

Question

Can the javascript shorthand for if-else return out of a function? If so how would this work.

eg. I have this:

if(boolean){
 return;
}

and I would like to write it as this:

(value)? return;

Chrome complains that return is unexpected. Is there anyway to write something like this so that it is valid?

Answer 1

No, you can't do that unless you return a value. For example if your function had to return a value you could have written:

return boolean ? 'foo' : 'bar'; 

But you cannot stop the execution of the function by returning void using the conditional operator.

Answer 2

If you intend to return from the function at this point in its execution regardless of whether the test evaluates true or false, you can use,

return (value) ? 1 : 2; 

But if you merely wish to return early when a test evaluates true (for instance, as a sanity-check to prevent execution when parameters are invalid), the shortest you can make it is:

if (boolean) return; 

Answer 3

if(boolean) return;

Single line , readable , perfectly valid;
