How about any => Object.prototype.toString.call(any).slice(8, -1)

I really like this package, because it not only uses the method you mentioned for checking types, but is written in TS, so you get the type checking feedback.

or even this

typeName = Object.prototype.toString.call

bit more self-explanatory `it => Object.prototype.toString.call(it).match(/^\[object (\w+)]/).pop()`
