DefaultMemoizeCache Class

Package: @esfx/fn

The default implementation of a MemoizeCache<A, T>, as used by memoize(factory, options).

Non-primitive keys have a lifetime scoped to both the life of the key (using a WeakMap) and the life of the cache. Results associated with a non-primitive key can be garbage collected if the key is garbage collected.

Primitive keys have a lifetime scoped to the life of the cache, so results associated with a primitive key can only be garbage collected if the cache is garbage collected.
