JavaScript JavaScript Basics (Retired) Making Decisions with Conditional Statements Using Comparison Operators

JavaScript

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'. Bummer! I don't see the message 'a is NOT greater than b'. Are you sure you wrote the conditional statement correctly? Preview Get Help Reset Code Recheck work script.js index.html

if ("a > b"), this is the issue, a>b is not a string.

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');
}

I see your problem was wrapping the conditional in a string

// correct
if (a > b) {
    alert("a is greater than b");
} else {
    alert("a is not greater than b");
}

// incorrect - don't wrap your conditional in quotes
if ("a > b") {
    alert("a is greater than b");
}
