Why isn't this code challenge working?

It's from the iterating through an array.

script.js
var temperatures = [100,90,99,80,70,65,30,10];
var count = 0;
while (count<temperatures.lenght) {
  console.log(temperatures[count]);
  count += 1;
}

You've got a typo in the code you posted here, might that be the hiccup? It's sometimes very hard to find simple things like that in code you've written since we tend to read what we meant. :)

var temperatures = [100,90,99,80,70,65,30,10];
var count = 0;
while (count<temperatures.lenght) { // length
  console.log(temperatures[count]);
  count += 1;
}
