Does it make sense to group the constants a little more? This module looks like it's a place where more constants could be added so maybe it makes sense to create to group them in a character or char object?

In general I agree but I personally think we should do that when it is time to do so instead of adding something before we need it.

@kfarnung I agree with @BridgeAR. Besides, I want to refactor similar places in the codebase, so I think I'll do it next time.

If we're planning to add more in the future, it makes the scope of any future change smaller and less risky. I don't have a strong feeling either way, mostly just an observation since the new file is simply internal/constants.js and in my experience those sorts of files get out of control before you know it.

nit: for readability it might help to change these comments to // style

@devdazed what about comment like this: // /? Now it's /*/*/

I would at least put spaces and quotes around them like /* 'A' */ which also makes the original suggestion less crazy since it would be // '/' which is at least a little clearer.

CHAR_LOWERCASE_A: 97, /*a*/
CHAR_UPPERCASE_Z: 90, /*Z*/
CHAR_LOWERCASE_Z: 122, /*z*/

// Non-alphabetic chars.
CHAR_DOT: 46, /*.*/
CHAR_FORWARD_SLASH: 47, /*/*/
CHAR_BACKWARD_SLASH: 92, /*\*/
CHAR_COLON: 58, /*:*/
CHAR_QUESTION_MARK: 63, /*?*/
};
