There's one more decision to make in the ruby style guide.

This section has two options, and the style guide recommends picking one: https://github.com/ActionSprout/coding-styles/blob/master/ruby.md#consistent-string-literals

I would be happy either way. I'd even be ok with removing this section of the style guide, as I don't think we are very consistent right now anyway.

This debate has been going for quite a while. Usually the arguments are like this:

• For single quotes:

  There's a slight performance improvement, since ruby doesn't have to scan the string for possible interpolations.

• For double quotes:

  It's likely that you will end up interpolating some strings and it's annoying to change them. The performance improvement is negligible.

To be honest, I'm not very consistent about this. Sometimes I feel like following the spirit of both rules and using single quotes for things that really are not likely to be interpolated, like strings that are identifiers (which would be a good case for using a ruby symbol, but sometimes that just doesn't end up being the case), and then double quotes for strings of text like copy or whatever, which seem to have a higher likely-hood of being interpolated in the future. However, these guidelines are too subjective to be in a style-guide. Hence the idea of just removing this section and not worrying about it.

Other notes: Our javascript (es6) style-guide requires using single quotes.

Thoughts?
