Would be nice to have TypeScript type definitions bundled in this package. The types should be strict and should be generic so it preserves the original function type.

The type definition should follow this styleguide, and should have full docs and type tests.

Some examples:

• sindresorhus/semver-regex@039944b
• sindresorhus/global-directory@0aae4d6
• sindresorhus/md5-hex@bbbfeff

Note that this is not an easy task and requires you to have advanced TypeScript experience. There have been multiple attempts and a lot of wasted time on my part in the past. If you intend to work on this, please look at the previous attempts and the feedback given there.
