TypeDetector

A class that holds a few simple predicate functions for detecting the native type of input.

Installation

Simply do: npm install typedetector.

Usage

const typeDetector = new TypeDetector();
if (typeDetector.isFunction(something)) {
	// something is typed as a function in here.
	something(arg);
}

The library only covers a few of the built-in types since instanceof checks covers the rest. But, for things such as strings, numbers and booleans, the predicates will be truthy if their object wrapper types is also used, e.g.:

typeDetector.isNumber(new Number(2)) // returns true

Changelog:

v1.0:

• First release. Contains a few methods for things that traditional instanceof checks doesn't cover.
