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

what does this mean?

I keep getting this as an error "There was an error with your code: ReferenceError: Strict mode forbids implicit creation of global property 'i' "

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

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

Hi Paul, it seems that there is a logic problem in your code : 1.The i variable is not declared 2.The condition of the loop should be until i is smaller than items.length 3.You need to increase i by one every time the loop run, otherwise you will get an endless loop Here is my code:

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