Got stuck here...i have no idea what i did wrong..

I even looked at the video again...maybe my brain just doesn't work today...

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

Hey!

You should replace i += 1 with i++. It does the same thing but i++ is a cleaner way to do it!

You made a spelling mistake in the word length, this is why it doesn't work!

Happy coding :)

:point_right: It looks like you misspelled "lenght" (should be "length").

And I believe your syntax of "i += 1" is generally considered to be preferred over Marco's suggestion of "i++" — both for more clearly representing the code's intentions, and for being less susceptible to undesirable side-effects.
