Key points (tl;dr):
.bind()method is very costly as it attaches the same event handler to every item matched in your selector.
.live()method as it is deprecated and has a lot of problems with it.
.delegate()method gives a lot of “bang for your buck” when dealing with performance and reacting to dynamically added elements.
.on()method is mostly syntax sugar that can mimic
.delegate()depending on how you call it.
.onmethod. Get familiar with the syntax and start using it on all your jQuery 1.7+ projects.
To proove: Agile projects are 3 times more successful than Waterfall projects.
Agile and Waterfall both are methodologies which define to develop successful project on time, on budget and in plan features. Comparison between them is not WHAT they are, BUT its HOW they do. Agile and Waterfall are differentiated in how effectively they utilize the processes.
