This reduces the runtime and makes sure the strict and loose options can be tested individually. Besides that a couple of redundant cases were removed.
This adds a smarter logic to compare object keys and it also skips the object key comparison for arrays, if possible. Besides that it adds a fast path for empty objects and arrays. It also adds a fast path for boxed strings and improves the comparison performance for TypedArrays with extra keys on the object. On top of that a few functions are now safer to call by using uncurryThis and by caching the actual function.
Currently the comparison could throw an error in case a boxed primitive has no valueOf function on one side of the assert call.
