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

Need help with JavaScript Loops, Arrays and Objects - Iterating through an array

I am attempting to iterate through this array with a for loop on a code challenge.

Not sure where I am going wrong but I keep getting an error that it needs to iterate all the temperatures or a communication error.

function listTemp(list){ for(var i = 0; i = list.length; i += 1){ console.log(list[i]); } }

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

listTemp(temperatures);

script.js 
function listTemp(list){
  for(var i = 0; i = list.length; i += 1){
    console.log(list[i]);
  }
}

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

listTemp(temperatures);

Hi David! The problem here is you are using the equal operator in your second stage of the for loop you are setting i to temperature.length where generally you want to test if i is less than or greater than something! Check it and let me know if you have any additional problem!

Cheers!
