You might not have been writing JavaScript. For objects, spacing properties from curly brackets is pretty much the norm, Prettier does that by default. For lists I see it rarer but I personally use it instinctively for consistency with objects, especially with things like useState destructuring and ([ complex, ...splatting, ...combinations ]) into function calls (which admittedly becomes uncomfortably terse).
