Condition Checking

If statement

We can use this statement if we want to execute a set of code in case the given condition is true. Let us say if today is Sunday go to market.

syntax (How it is written):

if (condition)

{

job to be done if condition is found true

}

Example

<html>

<head>

</head>

<body>

var a,b;

a=100

b=50

document.write("<br>Value of a "+a);

document.write("<br>Value of b "+b);

if (a>b)

{

document.write("<br>value of a is greater than b ");

}

</script>

</body>

</html>

Understanding program :

Value of a is 100 and value of b is 50. In if statement, we are checking that if a is greater than b then the message should be printed.

Output:

Value of a 100
Value of b 50
value of a is greater than b
