Add a conditional statement that tests if the value in the variable a is greater than the value in variable b.

Add a conditional statement that tests if the value in the variable a is greater than the value in variable b. If it is, pop up an alert with the message 'a is greater than b'; also add an else clause that pops up the message 'a is not greater than b'.

script.js 
var a = 10;
var b = 20;
var c = 30;

You need to use an if, else function.

First to test whether a > b and give an alert to say a is greater than b else alert that a is not greater than b.

The result should look something like this.

if (a>b) {     //statement checks is a is greater than b
  alert("a is greater than b");    //if a is greater than b this alert runs
} else {
  alert("a is not greater than b"); // if a is not greater than b this alert runs
}
