5,045 PointsConditional Statements using Alerts. Tried numerous syntaxes. Need to move on. Please help. Thnx.
Please see challenge. Self explanatory.
var a = 10;
var b = 20;
var c = 30;
if ( a > b) {
alert("a is greater than b");
}
else ( a !> b) {
alert("a is not greater than b");
}

33,512 PointsTwo things:
- "else" cannot have a conditional statement with it. It's just
else {. If you want to evaluate a second condition, you'd useelse if ( /* your condition here */ ) {. -
!>is not a valid operator. Please see the MDN page on JavaScript expressions and operators for a list of all the operators available. If you wanted to say "A is not greater than B," you'd probably want to simply write "A is less than or equal to B," which isa <= b. Or (a bit more awkwardly, but valid), you could write!(a > b)which is like saying, "It's not true that A is greater than B."
I understand you want to move forward, but it's important to spend some time studying this stuff and getting the foundations down. It gets a lot harder than this.

26,783 PointsHi Michael after looking over your code it looks to me that you have added a logic condition to your else statement. Which is not correct. The else statement doesn't require logic because when control gets to the else clause it means that none of the above logic has worked and control is going to fire the else statement.
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 hope this helps! vote it up if did! happy coding!
