var _this = this. It always does. I write it oh-so-often to keep my JavaScript scope hanging around – and the idiom no longer makes me cringe. It’s like an old friend. The only problem with my old friend is that Textmate doesn’t have the same feelings towards him as I do. He certainly won’t […]
It’s been a while since Slashdot was my regular hang out – so perhaps the demographic has swung radically – but I was amused (and a little bit incredulous) to see a stack of mis-informed javascript hate in the comments of an article talking about Harmony (TC39), the proposed next version of ECMAScript.

I’ve had a few queries about some of the code in my Hacker News bookmarklet – which makes use of some JavaScipt 1.6 & 1.8 features: map; reduce; filter; and forEach (sorry, no love for some or every this post). Superficially these are just array methods that take a function and apply it to each […]

But it seems browsers and devices aren’t 100% in agreement on either what a DOMTimeStamp is, or what it is when it comes back from a geolocation […]
The super-cool Google Jules Verne demo that went up today reminded me that I made an accelerometer tester for the iphone ages ago. It’s an offline app, so don’t be afraid to “add it to home screen” – and if you don’t want to get dizzy, then lock the phone to portrait mode! GO HERE […]
Inline event handlers… remember them?! Yes, they’ve gone the way of the blink tag and Adobe Flash, but recently I used one while debugging and realised: “Hey! I have no idea how to get the event object in an inline even handler!” and, shortly after “In fact, no idea how to write an anonymous function […]
