The smallest boolean in JavaScript

One of my projects has a pretty large API, with lots of methods returning boolean values. At first, I returned 1's and 0's - which are not actual booleans, but are certainly good enough (for most applications). However, for a public API, I knew they would need to return true or false... After making the edits, my file size jumped. Which is how I found the smallest boolean in JavaScript.

Proxy - You've come a long way, baby.

I began this post three weeks ago and should have published it then. For it has been an exciting three weeks, for me. I'm proud to announce Proxy, my first opensource JavaScript project, is available on github.com. Alas, this post is only about the journey to that destination...

Use JavaScript comment-urls instead of the traditional void(0) method

The longstanding compromise, between reducing inline JavaScript and preserving accessibility, has been to use "javascript:void(0)" in link hrefs and form-element actions. These elements and attributes are the hardened fall-back to DOM Level 2 events, and (unlike myself) many believe something must be there. Well the ubiquitous technique has a successor that is new to me. I'm no more excited about it's purpose, but glad something new has come along.

Saving to buy things

Remember how your elders would tell you to save in order to save? As in, "this money should never be spent"? Reality check: that's hard to do. Sure, I save money (all I can); I even save to save it. But then I need (ok, want) to buy something, and there goes my savings. That's normal, but the problem is I never spend my money on the reason I'm saving my money.

Inferring node placement via special sourceIndex values

I needed to know whether a node was in the DOM. Figuring there was a native property or method towards this end, I scoured Mozilla's documentation but could find nothing. Then Microsoft (yes, them) offered hope with Internet Explorer's sourceIndex property:

Retrieves the ordinal position of the object, in source order, as the object appears in the document's all collection.

sourceIndex (MSDN)

w3c browsers fire bubble listeners before capture listeners

In w3c browsers, the event object's eventPhase property may indicate when it is in capture or bubble mode with a 1 or 3, respectively. A value of 2 indicates that the event object is "at" or processing the target node. However, when the eventPhase is 2, the event's mode is fuzzy.

Internet Explorer doesn't bubble click events to the window

This is a simple one. I put some sample code on jsbin.com to show how IE doesn't bubble click events to the window, while w3c browsers do. This is important, because I would normally think to use the window as a "global event listener", not the document. Yeah, I learned this one the hard way.
