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

array items in order

The error to my answer says that the items don't print in order from 100 - 10. I just assumed that the items would print from i = 0 (the 0 index item on the array, which is '100'), until it finished at 10, which would be the array.length. What am I missing?

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

for ( i = 0; i < temperatures.length; i += 1 ); {
  console.log(temperatures[i]);
}

This is some problem in this line

for ( i = 0; i < temperatures.length; i += 1 ); {

You should have a var keyword before i declaration, also, NO semicolon before the {

for (var i = 0; i < temperatures.length; i += 1 ) {
