Loops and Arrays

Hi there does any one know what's wrong with my code?

This is what it's supposed to do:

Use a for or while loop to iterate through the values in the temperatures array from the first item -- 100 -- to the last -- 10. Inside the loop, log the current array value to the console.

This is my code:

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

It just does not work... To be honest, I am not sure why.

Thanks in advance for your help :)

Sincerely,

Eddy

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 Edgar,

The code is correct, you just have a spelling error in the for loop conditions. You have "lenght" instead of "length"

Fix that up and the rest is fine! :)

Nice work! :dizzy:
