  Best practices of front end optimization

1. Use DocumentFragment or innerHTML to replace complex elements insertion DOM operation on browser is expensive. Although browser performance is improved much, multiple DOM elements insertion is still expensive and will affect the page load speed. Assume we have an ul element on our page, we now want to retrieve a JSON list using AJAX and then update the ul using JavaScript. Usually we may write it as : var list = document.querySelector('ul'); ajaxResult.items.forEach(function(item) { // ...

  Why Windows?

Since the latest episodes of both Bent and Throw it Against the Wall have seen me mention Windows Phone 7, I think it’s about time I talk about why I like it. I know there’s a lot of scepticism surrounding it. And why not? Most people I know who were considering jumping the Microsoft ship did so in the dark days of Vista, so that’s their last experience with Windows. Anyone who saw their parents working on a Treo back in the nascent days of the Blackberry know the slop...

  Why Javascript is a Joy

I’m probably a bit biased – being a front-end web developer for a few years will do that – but I really enjoy writing Javascript. I’ve recently retreated from pure coding the last few months, but I got an opportunity this past week to jump back into some tasks, and it has reminded me how fun it is to dive into our[1] front-end codebase. Yes, Javascript can be surprisingly elegant yet completely infuriating, and all on the same line of code; for a long time, ...

  How I Develop Things and Why

I've always considered myself a bit of a software junkie. Nothing excites me more than a great piece of new software. Some of my best childhood memories are our trips to Grandma's house, where I'd have access to a computer with a dial-up connection that I'd use to obtain freeware and shareware. I'd bring 4 or 5 floppies with me and try to cram all the games, waveform editors, and utilities that I could sneaker-net home. Luckily today, excellent software written with passion oozes out of ...

  10 reasons why Dart is cooler than JavaScript

Dart is a new programming language from Google and after coding JavaScript for over one year now, I immediately felt in love with it. Coming from the Java world I had a good bunch of things I had to learn before I could use JavaScript. Some people say, you need to dig deep into JavaScript, otherwise you are not allowed to speak about the pros and cons of a language. I am not a JavaScript Ninja. But I strongly believe a programming language should be easy to learn, easy to understand and s...

  Web programs written in C++ are no big deal

I had an interesting conversation with a friend the other day. She wanted to try putting together a weekend "hackathon" just to see what we could build. It would be one of those fun things where we just start tinkering and see what comes out of it. Somehow, this conversation got to the topic of libraries, programming languages, and frameworks. Then it got a little weird. I guess the current "shiny" thing is still more-or-less Ruby, and particularly when used with Rails. Oh, I suppo...

  How To Make The Most of Your Least Productive Time

Everybody talks about mastering the art of staying productive. Not many people willingly accept that such efforts are futile. It’s impossible to stay productive 100% of the time, and this will never change. Something that I believe to be just as important, if not more so, is what we make of our least productive time. We all have the capacity to be extremely productive for some part of the day. Even the world’s grandest underachievers. But I believe that to be successful runni...

  â€œNative vs Web” Is Total Bullshit

The web is dead. HTML5 is the be-all end-all of the future. Users are spending more time on apps and less time on the web. You can do anything on the web that you can in a native app. Yawn. Here’s how I feel whenever I hear/read anything about the overplayed “Native Versus Web” argument: It’s not an either-or decision Why aren’t we still arguing over “Print vs Digital”? Well, because (most) people understand that each medium has its place in thi...
