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

I'm getting the error that I should log the numbers in order. The JS console shows all numbers are in order. Pls Help.

I thought I understood this lesson, but now I'm thoroughly confused.

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

var tempList="<ol>";

for ( var i = 0; i < temperatures.length; i += 1) {
 tempList += "<li>" + temperatures[i] + "</li>";
}
tempList += "</ol>";
console.log(temperatures);

Good job! You did what was asked, and then some. The challenge isn't looking for the <ol><li> tags wrapped around it. So you can simplify it to console.log(temperatures[i]) and put it inside the for...loop so it runs once for every array item. Wrapping with HTML is good for presentation, while logging to the console is plain text.

Thank you Tim and Steven! I thought I tried both ways, but I'm pretty sure I missed something. I tried the challenge 2 ways....

//Simplified as suggested and moving the console.log "inside" the loop.//

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

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

//AND keeping the ordered list and moving the console.log "inside" the loop.//

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

var tempList="<ol>";

for ( var i = 0; i < temperatures.length; i += 1) { tempList += "<li>" + temperatures[i] + "</li>"; tempList += "</ol>"; console.log(temperatures[i]); }

The challenge instructions say, "Inside the loop, log the current array value to the console", but the code here is building a string in side the loop and logging it after the loop.

Also, as Tim suggested, you would not use HTML tags when logging to the console. They do not perform the same job in the log as they do on the page.
