Very simple problem with booleans, PLZ help!

Im trying to start learning javascript in code academy. So I found out that I can't complete one task with booleans.
I will copy the task...

Write code that will say true if I'm coding like a champ! has more than 10 characters.

So my answer was:

if ("I'm coding like a champ!"length)>10=true

I have no idea in what order should I write these...

Please help!

The expression you want to evaluate must be contained in brackets.

Code:

var str = "I'm coding like a champ!"

if (str.length >10) {  // returns true or false

alert ("The length is over 10");

}

Code:

if ("I'm coding like a champ!".length >10) {

alert ("The length is over 10");

}

Quizmaster: What three-letter word means "at this moment"?
Contestant: Then.

The result of a comparison is a boolean, so that is what you must show:

alert( "I'm coding like a champ!".length > 10 )

Or to save the result

Code:

var result = "I'm coding like a champ!".length > 10 ;



alert( result );

Code:

var result = "I'm coding like a champ!".length > 10 ;



alert( result );

That might display 1 rather than true:

Code:

var result = "I'm coding like a champ!".length > 10 ;



if (result) alert( 'true' );

That might display 1 rather than true:

If you convert a boolean to a number, you'll get 1 or 0. If the result of an expression is a boolean, then that is what it will display.

alert( typeof ( "I'm coding like a champ!".length > 10 ) ) boolean
