jQuery Interview Questions and Answers

Ques 6. With jQuery UI 1.7 being released in the last few days, what do you see as the key parts of jQuery UI 1.7? What are you most proud of out of that release?

Ans. The one thing I'm most proud of is that our framework has matured so much since 1.5. We have taken great care to unify our API, fix hundreds of compatibility and behavior issues, and now we truly have a foundation to build upon without needing to rewrite the core functionality again and again. This will allow us to push our features in the next releases in literally no time.

Ques 7. What were the biggest challenges of getting the 1.7 release out there?
Ans. Our test coverage is still incomplete, and with every fixed bug, we introduced 2 others, which made the arrival at a stable level extremely difficult. Every week, there were some 50-100 bugs entered in the bugtracker, and there was literally no end. Luckily, we were able to triage the bugs to critical and blockers and solve these in time for a release. You have to have a lot of guts to push out a release that's still imperfect - but an imperfect release is better than one that gets delayed for months. You can always roll out 1.7.1.

Ques 8. Jumping off of jQuery UI for a second, Do you release early, release often with all of your projects? What are your thoughts on that strategy?
Ans. Speaking for myself, I often release too early. That has been a problem in the past, when we released versions as stable that weren't, for instance. So it's important to find a combination of both - a stable release must be stable, while development cannot be halted or blocked through stubborn processes. A labs section is great in that way - it allows developers to contribute freely and plan on an open canvas, with early preview releases, and the work can later be merged back.

Ques 9. Have any of your startup projects failed dismally - if so, why and how did you learn from them?
Ans. A lot of my side projects failed, as a matter of fact, while others succeeded. Usually, the reason why some project fails is not a technical one, but the fact that one didn't build meta data around it. That means a dedicated site, documentation, instructions.

Ques 10. Mac, Windows or Linux? Why do you love this platform while using jQuery?
Ans. I switched to Mac hardware around a year ago and I�m totally in love with it. All components work together nicely, and so far, I never had to return my Macbook Pro to the Apple Store because of an issue. However, I�m still using Windows through Parallels because OSX, while visually nice and stable, has fundamental usability flaws. One of these flaws is the Finder. I recently worked on the jQuery UI Selectables in the labs version, and once again saw that the Finder had great flaws when it comes down to selection. For instance, if you select multiple items and click on one of them, the multiple selection isn't cleared. Also, my tools that I love for windows simply don't have an alternative yet.
