Do read about the Day 1 of the conference, if you haven’t already.
The day began with a keynote on ‘Common jQuery Mistakes’ by Dave Methvin – President of the jQuery foundation, who spoke at length about the common pitfalls all developers tend to find themselves in quite often. Dave also spoke on the coding do’s and don’ts that would have a bearing on the page performance. The session also detailed on managing the various jQuery versions out there, being aware of the features that are either supported or deprecated, how jquery-migrate would help mitigate issues in migrating our applications from one version of jQuery to the other. The essence of the talk was that the latest version of jQuery may not be always well suited for our applications and that care needs to be taken in choosing the right version often going through the documentation and which seldom developers do these days. The keynote ended with several code snippets demonstrating the mistakes committed therein and a way out of all those mistakes. The session met with a thunderous applause from the eager audience.
