gistfile1.js

// For each of the following code fragments:
//  a. what does the code do?
//  b. what did the author intend for it to do?
//  c. how would you fix it?
// NOTE: all code samples work exactly the same in all browsers

// 1. object literals
var data = [ { high: 100, low: 81 }, { high: 93, low: 73 }, { high: 60, low: 32 } ];
function getAverages(data) {
    var avgs = [];
    for(var i = 0; i < avgs.length; i++) {
        avgs.push(data[i].high + data[i].low / 2);
    }

    return avgs;
}
getAverages(data); // returns [];

// 2. list of links 
var p = document.createElement('p');
for (var i=0; i<10; i++) {
    var a = document.createElement('a');
    a.innerHTML = "link " + i;
    a.onclick = function() {
        alert("you clicked link " + i);
        return false;
    };
    p.appendChild(a);
}
document.body.appendChild(p);

// 3. method callback
var bob = {
    firstname: "Bob",
    greet: function() {
        alert("Hi, I'm " + this.firstname);
    }
}
window.onload = bob.greet;

Haha, you're right. Good catch.
