Refactor to be more in line with SRP

[kolyaventuri]

Currently the package is defined in a single index.js file. Though it is a small package, it could be refactored to clean up the codebase and be more in line with single responsibility principles. For instance, there are some nested ternaries and an add method is defined within the function export.

I would be willing to take this on and submit a PR, if that's alright!

[sindresorhus]

Sure, good idea, but I think the two open PRs should be merged first.

Would you be able to help review #25?

[kolyaventuri]

Absolutely! We can leave this one on hold until the other two PRs are merged. I'll take a look at 25

[sindresorhus]

This can now be done if you're still interested @kolyaventuri :)

[kolyaventuri]

I'll take a stab at it!

[sindresorhus]

@kolyaventuri Still interested?

[kolyaventuri]

@sindresorhus hi! Yes, absolutely. Apologies on never getting back to this 😂

[sindresorhus]

Bump :)
