Description of the problem

webgl_animation_multiple example doesn't follow Three.js code style.

I'm glad if someone cleans up.

@strazdinsg Any interests in doing this? 😇

[takahirox]

Ah, sorry I had a change of heart and did by myself. Making PR now.

Thanks for reporting, I did not know about the code style guide. Will know next time :)
@takahirox How did you update the style? Configured IDE with the rules from the document and did auto-format?

BTW, I see there is a rule about naming: ConstantsLikeThis. In the file I created CONSTANTS_ARE_LIKE_THIS, probably should be renamed?
I will take a look at the rules and check if the example follows them. Will create a PR in case I find necessary changes.

I manually edited because I don't use IDE to write JavaScript.

I know some modules use CONSTANT_NAME style, for example GLTFLoader. I think renaming them may be good for code consistency.

[strazdinsg]

We could ask @mrdoob why the constant naming rule is so weird, I have not seen ConstantsLikeThis anywhere else. But I know that one should not question coding convention, just use the one that has been decided "by the board" :). @mrdoob, in case there is an error in the style document and you actually meant CONSTANTS_LIKE_THIS, let us know :)

[mrdoob]

I don't have a preference. CONSTANTS_LIKE_THIS look good to me.

[takahirox]

I prefer CONSTANTS_LIKE_THIS. Do you mind if I update the code style wiki page?

Do you mind if I update the code style wiki page?

Go for it.
