  TLDR:

  Trailing commas for lists allow easier:

  • merging of code
  • rearranging of items in the list.

  Commas aren’t the only thing that need similar treatment. For example, Typescript allows a leading | for union types, and for union types split across multiple lines, the result is so much easier to format compared to the equivalent code in, say, Haskell.

  SQL needs more trailing commas so fucking badly.
