    # This makes it so we can have trailing commas in tsconfig.json files,
    # though as noted in https://github.com/prettier/prettier/issues/5708,
    # two things are suboptimal:
    # - "quoteProps" does not have an "always" option, so "preserve" is the
    #   best we can do.
    # - If your string contains an escaped double-quote, Prettier will rewrite
    #   it as a single-quoted string to avoid the escaping. The recommended
    #   workaround is to use `\u0022` instead of `\"`.
