- I recently added a bunch of strict rules to our eslint plugin around returns: ca9af37866
- These mostly are issues that occur whilst writing code, that you spot and fix as you're developing, but they're annoying to notice/find and eslint can be used to flag them quickly
- There are of course, edge cases where you don't need to return from array fns, but this rule also suggests better patterns might be available
- For our excert helper and new assertEvent helper, I've updated the code to use simpler patterns that are easier to read, so as to avoid the warnings
- For our old API I've simply disabled the rule as we're about to delete this code
