code challenge: arrays in javascript deep dive

the code challenge says: Set the 'guides' that has placeholders for 42 elements but has no values stored in it.

I tried doing the array constructor, var guides = new array(42); but it said null.

I tried var guides = [1,2,3,] etc.. up to 42 but it said you have 0 undefined values, expecting 42

any suggestions? I didn't hear any thing about place holders in the video, I think that's what's throwing me off.

thanks!

var guides= new Array (42);

it turns out that "placeholders" just means they want commas. you have to make the array with 42 commas in it.
