Why's this simple object not working?

[javascriptnewbie]

1: Do do you actually do with objects?
Aren’t they the same thing as functions?

2: Why’s this not working?

Thanks!

we have two ways to create object in JS:

var obj = new Object(); 
       obj.height = 10; 
       obj.width = 20;

second, more often used:

var obj2 = { 
       height: 10, 
       width: 20 
}

I just tried the second one and it doesn’t quite work as expected :(

var object-name = {
height:10,
length:10
}

alert(height+length);

var myObj = {
  a: 10,
  b: 20
}

alert(myObj.a + myObj.b);

Edited to add: With javascript use CamelCase style when writing variables.

// Bad
var my-bad-var-has-dashes

// Good
var myGoodVarNoDashes

Thanks very much, sir. I appreciate you helping me.
