JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Iterating through an Array

Getting error, don't know what for? Everything seems in order?

This is the error: Bummer! There was an error with your code: TypeError: 'undefined' is not an object (evaluating 'console.log._args[i]')

It's abit frustrating because I have no clue whats wrong, and I'm even seeing the same loop in the previous video before this challenge. I feel like i'm blind. Appreciate any help!:)

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]);
}

Hi there! You simply have a spelling error. You typed temperatures.lenght instead of temperatures.length. Note the spelling of "length" as oppose to "lenght".

Hope this helps! :sparkles:

Thank you, after being through so much code I missed it. Now I'll look more carefully into those situations in the future!:)
