on.js

The fun part of user scripting is deciding what happens. The boring part is scavenging the DOM for bits of templated data, or elements you want to mod.

Have on.js do it for you!

(tl;dr DOM builders like [domo][domo] trump HTML templates on the client.)

Like all web developers, I've used a lot of template engines. Like most, I've also written a few of them, some of which even [fit in a tweet][140].

The first open-source code I ever wrote was also one of the the first template engines for node.js, [a port][node-tmpl] of the mother of all JavaScript template engines, [John Resig][jresig]'s [micro-templates][tmpl]. Of course, these days you can't swing a dead cat without hitting a template engine; one in eight packages on npm ([2,220][npm templates] of 16,226 as of 10/19) involve templates.

John's implementation has since evolved and [lives on in Underscore.js][underscore], which means it's the default choice for templating in Backbone.js. And for a while, it's all I would ever use when building a client-side app.

But I can't really see the value in client-side HTML templates anymore.

    else if (start > end) {

        start = end;
        end = s;

###
  Usage: $(node).shortNumber(4711) sets the contents of `node` (to "4.7k")
         $(node).shortNumber() reads that actual number back from the node

  If you want to pre-shorten some DOM node with a value on the server side,
  be sure to set the data-shortNumber="4711" or whatever number on it, too:

  Likes: <span data-shortNumber="<% _num %>"><% short_number _num %></span>

  (To just format arbitrary numbers to tiny strings use shortNumber(4711).)
