Code creates new features & bugs and they usually come together, but it also needs to be optimized, cleaned up and secured to keep it running for years.
I made a large overhaul of all my code recently to remove external libraries such as jQuery for speed, simplicity, safety and to keep the code base small. Essentially jQuery was great at the beginning to help developers produce code that would work on all browsers, but since then browsers have become more compatible and adopted many of jQuery’s features.
This was no easy task and it took months and several phases to do this because many other widgets rely on jQuery such as date and time pickers in my calendar extension.
You can now enjoy the latest versions of all my extensions which are now faster and smaller, yet just as feature rich. In fact the date & time pickers are now custom made and more powerful with duration times, theme support and full internationalization.
