Chork NPM | npm.io

About

Chork is a minimal library for checking data types in javascript.

Typeof typeof works well, but only for variables of the primitive type and not for structures like Array, Date and others. Chork solves this by bringing the real type of past value.

Installation

Using NPM

npm i chork

Using Yarn

yarn add chork

Use

Currently, chork has two test functions which are check and checkAll.

check

It receives only one argument of any kind.

import { check } from 'chork'

check(1) // 'number'
check('foo') // 'string'
check([1, 'foo']) // 'array'
check({ key: 1 }) // 'object'
check(new Date()) // 'date'

checkAll

The checkAll function works in the same way as check, the only difference is that it returns an object with a key being its own value and a value being the result with the type of data tested.

import { check } from 'chork'

checkAll(1) // { '1': 'number' }
checkAll('foo') // { foo: 'string' }
checkAll([1, 'foo']) // { '1': 'number', foo: 'string' }
checkAll({ key: 1 }) // { key: 'number' }
checkAll(new Date()) // { 'Sat Feb 06 2021 12:35:41 GMT-0300 (Brasilia Standard Time)': 'date' }
