Iterating through an array

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.

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

You spelled length wrong and didn't declare i in the for loop. Also you didnt loop through the array but wanted to start on 100. Have some more practice with for loops and you'll get it! Meanwhile, it should be something like this: 

var temperatures = [100,90,99,80,70,65,30,10];

for (var i = 0; i < temperatures.length; i++) {
  console.log(temperatures[i]);
}
