Question: Type guards duplicated with the is

[younho9]

is provides type guards when using with TypeScript.

There are some duplicated functions like isFinite, isInteger, isSafeInteger. (Currently is does not seem to provide a type signature for the above functions.)

I wonder if is and ts-extras have different plans for type guards.

The packages have different goals. There is a small overlap, yes, but only for a few functions.

Can you open an issue on is about that? I would be happy to see those methods have better type-guards.

I think type guards in this repo should be work better for Array.prototype.filter and Array.prototype.every?
