Ternary Operators
How to use ternary operators in javascript?
Explanation
Ternary Operator:
As the name indicates ternary operators take three operands. The syntax is condition ? result1 : result2;.
Here you use a condition before question mark (?) followed by result 1 and result 2 separated by a colon (:). Result1 is called if the condition is satisfied else result2 is called.
<script language=javascript>
var b=5;
(b == 5) ? a="true" : a="false";
document.write(" --------------------------- "+a);
</script>
<script language=javascript>
var b=true;
(b == false) ? a="true" : a="false";
document.write(" --------------------------- "+a);
</script>
