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

I am using: if("a " > "b")... and getting an error reminding you to use '>'?

Despite this the alert boxes are working fine, and popping up in my browser just fine. I've tried multiple variations: if('var a' > 'var b')...and so on. Any help would be great!

script.js 
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');
}

you need a lowercase "i" in if.

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');

There this works!

First: if shouldn't be capitalized.

Second: By putting the quote marks around a and b you are comparing the the literal strings "a" and "b", not the variables a and b. To compare the variables you need to leave those out like this:

if (a > b) {
  // ...
}

This is what your code should look like if it's done right.

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');
}
