Javascript Ternary operator with empty else

Question

I\'m trying to convert the following if-else to it\'s ternary operator representation in javascript as follows

var x = 2;
if (x === 2) {alert(\"2\");}
else
          


        

Answer 1

I don't like it's either. So you're on the right track looking for alternatives.

In this case, I would write:

t===2 && alert("2")

Your idea is valid too, for instance you can do this:

t===2 ? alert("2") : null

But it's four extra chars.
