Honestly, I don't really mind. The other pr was probably too tailored around the needs for sv, but we can still totally do this with this api and just abstract it away. I don't see any notable differences to #79 so I'm happy if we wan't to proceed with this.

This is an alternative to #79 — rather than passing in a
WeakMap, which is arguably a bit of an unusual API, this adds two new function options —getLeadingCommentsandgetTrailingComments. Both receive aTSESTree.Nodeand return either aBaseComment[]orundefined.I find function-based APIs tend to age a bit better, because they can be hammered into whatever shape you need that day. Obviously you can still use a
WeakMapon the consumer side if you prefer (just pass a function that reads from the map), but it's no longer required.Another reason I like this approach is that we don't need to add a new type with a
positionproperty — we can just the same types that are commonly found in the (TS)ESTree ecosystem.
