- _.endsWith -> String.endsWith
- _.concat -> Array.concat
- _.each -> Array.forEach
- _.filter -> Array.filter
- _.map -> Array.map
- _.some -> Array.some
- _.has -> `key in Object`
- _.defaults -> Object.assign
- _.get -> `?.` and `??` (optional chaining and nullish coalescing)
- refactor: replace fairly complicated `expandIncludeWithDirs` func to
just use a few simple `forEach`s
- not as FP anymore, more imperative, but much simpler to read IMO
- refactor: add a `getDiagnostics` helper to DRY up some code
- also aids readability IMO
- a few places are still using lodash, but this paves the way toward
removing it or replacing it with much smaller individual deps
- _.compact still used because Array.filter heavily complicates the
type-checking currently
- _.isFunction still used because while it's a one-liner natively,
need to import a function in several places
- also the package `lodash.isFunction` is lodash v3 and quite
different from the v4 implementation, so couldn't replace with it
unfortunately
- _.merge is a deep merge, so there's no native version of this
- but we may remove deep merges entirely in the future (as tsconfig
doesn't quite perform a deep merge), or could replace this with a
smaller `lodash.merge` package or similar
