Adding to the above @neozenith, thoughts on this PR also including a run of eslint across the code base? I know lint PRs generally cause a lot of noise, but it'll be a pain we introduce on this PR, or the next person to raise PR against the repo once the check is in place

edit; I'm also happy to author that change-set if we want to keep it seperate
