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

You putted a lot of useless parentheses, and the best NULL value in js is undefined.

document.getElementById('btn-ok').onclick = function(){
  var val = document.getElementById('txt-val').value;
  
  val == 2 ? alert(val) : undefined;
}

Ok

using a single line if statement is better though

if(value === 2) alert(value);
