conditional statements

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'.

how do I do that?

thank you

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

if (10 > 20){
  alert("a is greater dan b");
}else{
    alert("a is not greater than b");

Hi there,

I have noticed in your code you have placed the actual values in the if condition. You can replace these values with the variables a and b which represent these values. Here is the below code if you are unsure:

var a = 10;
var b = 20;
var c = 30;

if (a > b) {
  alert('a is greater than b');
} else {
  alert('a is not greater than b');
}

Happy coding!
