autoplay attribute on videos is wrongly camel-cased

[rmfarrell]

JSX ignores the HTML autoplay attribute and warns it should be autoPlay.

Camelcase here is incorrect. I should only expect to use camelcase if the attribute were hyphenated in vanilla HTML. Autoplay is one word both as an html attribute and according to English.

Here is the list of attribute names:

The DOM Api method name for the video element is autoplay and I believe that would be more correct to use.

There seems be a convention of camel-casing the attribute names.
All the words starting with auto are camel-cased.

A change might require a breaking change unless it is backward compatible, meaning supporting both autoplay and autoPlay.

I don't know whether the ship has sailed and this is the idiomatic approach to follow or whether it is a good idea to be flexible and also allow autoplay.

Hi @rmfarrell!
You can read the reasoning behind using camelcase here and specifically about autoplay here

[rmfarrell]

I'd say accept both but deprecate the camel case way in a later version? camel case is for concatenating multi-word properties, but autoplay is one word. I was stuck for several minutes on this because there I would never have guessed that autoplay would be camel-cased just because it starts with "auto."
