Using a list var in printing array in the console. Challenge 1 Help?

Working on Challenge 1 and they are asking me to take a list of temps and iterate them in order from first to last on the console log. Please take a look at my attempt. I am honestly copying from the video because I assumed I would just need a for loop. but it shot it back at me saying they could not find a list variable. What is the point of the list variable? It is not asking for an ordered list of the items or I would create one. If you could just explain what the question is really asking that might help! :) Thanks everyone!

var temperatures = [100,90,99,80,70,65,30,10];

function list ( message ) { console.log (message); }

for (var i = 0; i < list.lenth; i+= 1){ console.log(temperatures[i]); }

script.js 
var temperatures = [100,90,99,80,70,65,30,10];

function list ( message ) {
  console.log (message);
}

for (var i = 0; i < list.lenth; i+= 1){
  console.log(temperatures[i]);
}

var temperatures = [100,90,99,80,70,65,30,10]; function list ( message ) { console.log (message); }

for (var i = 0; i < temperatures.length; i+= 1){ list(temperatures[i]); }

There were 3 things: length misspelled, need the length of temperatures not list, need to pass temperature[i] to the list function.

I hope this helps.
