What up with my code

Just trying this out but it doing nothing is the code wrong somewhere ?

var playlist = ["one", "two", "three"];

function printList(list) {
    var htmlList = "<ol>"
    for(var = i; i < list.length; i+= 1) {
        htmlList += "<li> " + list[i] + " </li>";
    }
    htmlList += "</ol>";
    document.write(htmlList);
}

printList(playlist);

the html is just a standard page linked to this js file

Hi Simon,

Just a few small modifications to your function here:

  • After you've create your htmlList variable make sure you close that line with a semicolon.
  • Starting your for loop var shouldn't equal i it should equal 0 so you start at the beginning of the array you're iterating over.

I hope that helps.

var playlist = ["one", "two", "three"];

function printList(list) {
    var htmlList = "<ol>";
    for(var i = 0; i < list.length; i += 1) {
        htmlList += "<li> " + list[i] + " </li>";
    }
    htmlList += "</ol>";
    document.write(htmlList);
}

printList(playlist);
