typeOf.pddivine

A library that intuitively identifies a variable's type and return the cooresponding type constructor or special value.

Features

Returns intuitive type of a variable. For example, the native 'typeof' function will return 'object' when detecting the type of an array variable. This typeOf library would return the native Array object constructor in this case.

TLDR;

const typeOf = require('typeof.pddivine');

const tests = [
  '',
  1,
  {},
  [],
  true,
  new Date(),
  function x () {},
  null,
  undefined
];

// Using 'asString: true' option.
tests.forEach(v => console.log(typeOf(v, { asString: true })));

/** PRINTS
* 'string'
* 'number'
* 'object'
* 'array'
* 'boolean'
* 'date'
* 'function'
* 'null'
* 'undefined'
*/

// Normal, without config option.
tests.forEach(v => console.log(typeOf(v)));

/** PRINTS
* String constructor
* Number constructor
* Object constructor
* Array constructor
* Boolean constructor
* Date constructor
* Function constructor
* null
* undefined
*/

Variance From Native 'typeof'

The native 'typeof' function has these two correct, but unintuitive, responses.

| Input Value Type | Return Value | | ---------------- | ------------------------- | | Array | String Value 'object' | | Null | String Value 'object' |

The native 'typeof' function also returns a string response for the type. The typeOf library will instead return the cooresponding constructor or special value to the identified input type.

TypeOf Library Evaluation of Type

| Input Value Type | Return Value | | ---------------- | ----------------------- | | Array | Array Constructor | | Boolean | Boolean Constructor | | Date | Date Constructor | | Function | Function Constructor | | Null | Special Value Null | | Number | Number Constructor | | Object | Object Constructor | | String | String Constructor | | Symbol | Symbol Constructor | | Undefined | Special Value Undefined |

Evaluating a Special Value Returns Itself

| Special Value | Return Value | | ----------------- | ----------------------- | | Null | Itself | | Undefined | Itself |
