Light-weight utility module for comparing and validating ES6 primitive and reference data types: Array, Boolean, Function, Number, Object, String, Symbol, Null, Undefined.

Installation

Using npm:

$ npm install --save aire-check

Using yarn:

$ yarn add aire-check

Usage

In Node.js:

import Check from 'aire-check'

let check = Check.equals(100, '100')  // true
check = Check.strictEquals(100, '100')  // false
check = Check.equalsIgnoreCase('hello', 'HELLO')  // true
check = Check.isArray('hello')  // false
check = Check.isArray(['hello'])  // true
check = Check.isEmpty({})  // true
check = Check.isNullOrUndefined(null)  // true
check = Check.isNullOrUndefined(undefined)  // true
check = Check.isSymbol({'value': true})  // false
check = Check.isSymbol(Symbol('hello'))  // true
check = Check.numbersOnly(100, 200, '300', 400)  // throws 'TypeError'
check = Check.numbersOnly(100, 200, 300, 400)  // no error
check = Check.booleansOnly(true, false, false, true, 'false', true)  // throws 'TypeError'
check = Check.booleansOnly(true, false, false, true, false, true)  // true
check = Check.stringsArrayObjectsOnly('hello', [1,2,3], 100, {'value': true})  // throws 'TypeError'
check = Check.stringsArrayObjectsOnly('hello', [1,2,3], {'value': true})  // true
