@stackmeister/types

Minimalistic and strict utility functions for JavaScript's primitive types.

Install

// Yarn
yarn add @stackmeister/types

// NPM
npm i @stackmeister/types

TypeScript typings are included (No @types/ package needed)

Usage

Predicates for simple type checks

import {
  isUndefined,
  isNull,
  isNullOrUndefined,
  isBoolean,
  isString,
  isNumber,
  isInteger,
  isNumeric,
  isArray,
  isObject,
  isFunction,
} from '@stackmeister/types'

isUndefined('test') // false
isUndefined(undefined) // true
isUndefined(null) // false

isNull('test') // false
isNull(null) // true
isNull(undefined) // false

// etc...

Notice: In the Stackmeister typing mindset, objects and arrays are two very different things An object will not be an object, when it is an array. It will only match the isArray predicate.
