I feel a little confused about the naming of keywords in js

Sometimes it is like this: getElementById, indexOf, charCodeAt, parseFloat, navigator.appName, navigator.appVersion/appCodeName/cookieEnable/userAgent, which gives the impression that it is the first letter of the word. Uppercase

Sometimes it looks like this: fontsize, fontcolor gives the impression that they are all lowercase

But sometimes it looks like this: innerHTML

Can anyone tell me about this? Is there any pattern? I think if I don’t use it for a while, it will get lost. Waiting for answers online!
