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

How do you solve this challenge?

This is what I've got so far:

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

for ( var i = 0; i <= [0]; i >= [7]; ) { console.log(i); i += 1; }

Can anyone help?

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

for ( var i = 0; i <= [0]; i >= [7]; ) {
  console.log(i);
  i += 1;
}

Here's a few hints:

  • the index value (i) should be compared with numbers (like 0) and not arrays (like [0])
  • the third clause of the loop can be where you increment the index
  • you could use the length of the array to control loop repeating
  • you don't need to increment inside the loop body if you use the third clause for it
  • the third loop clause should not have a semicolon after it
  • log out the array value instead of the index
