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

Your code is...

var temperatures = [100,90,99,80,70,65,30,10];
for (var i = 0 , i<temperatures.lenght, i+=10) {
  console.log( temperatures[i] );
}
  1. You must separate the elements in a for loop with semicolon ie. ; and not comma.
  2. lenght should be length
  3. You do not need to increment i by 10 as you won't print out all the elements from 100 - 10 that way. Your array has numbers from 100 - 10 and you want to go through all these numbers so you have to increase i by 1 each time so "i+=10" has to be "i+=1"

I hope this helps you sort it out.

something's wrong again

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

You shouldn't have changed temperatures[i] to temperatures in the console.log()
