Code challenge Conditional Statements JavaScript

Hi community

Can anyone help? I'm working my way through JavaScript and I've come to a code challenge on conditional statements. I don't understand why this is wrong. Any suggestions welcome.

The question is; 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'.

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

if ("var a" > "var b") } window.alert("a is greater than b"); } else { window.alert("a is not greater than b"); }

Thank you

"var a = 10" you use it only to create the variable which you did right. Now to call it you will need to use only "a" with out var. so:

var a = 10; var b = 20; var c = 30; if(a > b){ window.alert("a is greater than b");}else{ window.alert("a is not greater than b");}

hope this helps!

A few things:

  • When referencing a variable that's already been declared, you only need to refer to it by name, and not with the "var" keyword or quotations. So instead of "var a" > "var b", all you need to write is a > b.
  • The bracket you wrote after your first conditional is facing the wrong way.
if (a > b) {
    window.alert("a is greater than b");
} else {
    window.alert("a is not greater than b");
}

Hope that helps!

Looks like your brackets are turned around in the first statement. But also as Ben mentioned, you just need to refer to the variables by name (a, b, or c) rather than ("var a"). If you add quotes around these variables, JS will think that you are passing in the literal text "var b," rather than the value you stored for b.

Did you mean:

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

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