This is my script:
document.createTextNode
prevents text from being rendered as html.
Try this instead.
/*jslint browser:true */
var i;
var out = document.getElementById("output");
var args = ["aaa", "bbb", "ccc", "ffffd", 1, 2, 4 + 4];
function displayArgs() {
"use strict";
for (i = 0; i < args.length; i++) {
out.appendChild(document.createTextNode(args[i]));
out.appendChild(document.createElement("br"));
}
}
displayArgs(args);
