Hi I am having trouble figuring this out

const temperatures = [100, 90, 99, 80, 70, 65, 30, 10];
let item = '';
for (let i = 0; i < temperatures.length; i++) {
 item += `${temperatures[i]}`;

The template literal converts the number value into a string, and the += operator keeps expanding the string. Neither of these were asked for in the instructions.

The challenge is very simple, to "log the current array value", one at a time, as a number.
