Notes

1. Although this package is inspired by lodash, the method names might not be exactly the same or have different usage API, so make sure to read the docs first before using it.
2. The methods do not type check at runtime (e.g. The Array chunk method assumes the size parameter is always a valid positive integer) so make sure you pass the correct values based on the documents/typescript types.
