Javascript/DOM event name convention

Question

When I started doing web development, I realized Javascript event names were all in lower case with no separators, i.e. \"mousedown\", \"mouseup\"

Answer 1

As far as I can tell, there is no official practice regarding that subject. It seems to me that since camelCase is the generally accepted standard for names in js, that the same would apply with event naming. However, as you noted, js itself and many libraries do otherwise. I have seen both conventions used by great programmers, so I believe it is simply inconsequential. In the case of "the longest JavaScript event name ever" that's a great example of an event that should have used camelCase, in my opinion...or maybe they could have just shortened it :)

If you want to stick to what you've seen more often, use lowercase. If you think that's hard on the eyes (I do), use camelCase. I probably wouldn't use anything else if you're trying to conform to a standard.
