An Ant Task to Comment Out console.log Calls from JavaScript Files

As someone who started out doing JavaScript in the 1990s, I’ve been through the dark ages of debugging. Alerts, logging application data into DOM elements, etc. After having been through all that doom, I’m clearly a fan of console.log. I use it all the time. I bet you do too. It’s super useful.

The one downside? Leaving calls to console.log into code that’s being tested (as in, QA) or is destined for production (as in, emergency bug fix.) With Firebug or a similar tool running, you’re fine. Without it?

"console" is not defined.

I’ve seen this more times recently than I care to admit.

I Added Keyboard Navigation to my Site

Kind of a fun little exercise. Now I just need to figure out a nice way to hint to people that they can navigate with the keyboard.

Check it out. Start here and hit your right arrow key until you start to see the same things twice.

Based on shortcuts.js

I’m Presenting on CSS in October

I haven’t posted about this yet. I’m an incredible idiot. I’m presenting at the Boston PHP group in October. My presentation is a couple of weeks before Steve Krug. No pressure.

I hope to see you there 🙂

Book Review: High Performance JavaScript

I read High Performance JavaScript when it came out. It took me a while to write this review.

I’ve been busy (day job x spending a lot of time outside because it’s summer = less time for writing)

Anyway, it’s really good. It’s short, but well-written and focused so it’s an easy book to dive into, digest and integrate into your day-to-day.

One of the things I liked about it is that the topics cover enough ground that even as an experienced/expert developer you can learn some things that you’ve probably never run into in a production environment. Maybe you haven’t dealt with a lot of heavy-duty string manipulation and regular expressions or possibly you haven’t done a ton with build systems. They’re covered here, by experts. You might not be an expert after reading it, but you’ll definitely have enough to go on to start working in some solid enhancements into your own code.

All in all, this is a recommended book for all intermediate to expert JavaScript developers. It will get you thinking about your own code, about convenience and about JavaScript performance in a very fundamental way. That’s good for you, for your users and for the web as a whole.

I’m Going to Enjoy Writing Code for Internet Explorer 9 (I Can’t Believe I Just Typed Those Words)

In case you missed it the latest Internet Explorer 9 Platform Preview is out and it’s a thing of beauty. It added Canvas support so the first thing I did was run it through some demo code. It’s faster than Chrome. Visibly faster. No benchmarks needed. It’s such an incredible difference from the current Internet Explorer family which are many times slower than the good browsers out there.

The good news doesn’t stop there. There’s actual standards support.

PPK enthuses:

In the past few days I’ve been revising the CSS compatibility table with information about the latest crop of browsers. There’s no doubt about it: this is IE9’s show. It just supports nearly everything. No hassle, no buts.

And then enthuses some more:
