Ternary operator:

The ternary operator, as the first name indicates, requires three operands.

Grammar is a condition? Result 1: Results 2;. Here you write the terms on the question mark (?) followed by a colon (:) separated by a result of 1 and result 2. Satisfies the condition the result 1 otherwise the result 2.

<script type= "Text/javascript" > 

var b=5; 

(b = = 5)? A= "true": A= "false"; 

document.write ("---------------------------" +a); 

</script>

Result:---------------------------True

<script type= "Text/javascript" > 

var b=true; 

(b = = False)? A= "true": A= "false"; 

document.write ("---------------------------" +a); 

</script>

Result:---------------------------false
