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

  bit more self-explanatory `it => Object.prototype.toString.call(it).match(/^\[object (\w+)]/).pop()`
• nsonha 5y ago
  or even this typeName = Object.prototype.toString.call

  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. https://github.com/sindresorhus/is https://github.com/sindresorhus/is
