Synopsis

Ch.js is an open source type checking library for Javascript.

Motivation

The goal of this library is to provide an easy way to check if a variable is what it is supposed to be. Function, object, ascii, boolean, integer, string, json, email...

Installation

npm

$ npm i @lcluber/chjs

Yarn

$ yarn add @lcluber/chjs

Usage

ES6

import { isFunction, isArray } from "@lcluber/chjs";

if (isFunction(variable)) {
  //variable is a function
}

if (!isArray(variable)) {
  //variable is not an array
}

CommonJS

const ch = require("@lcluber/chjs/dist/ch.cjs");

if (ch.isFunction(variable)) {
  //variable is a function
}

if (!ch.isArray(variable)) {
  //variable is not an array
}

IIFE

<script src="node-modules/@lcluber/chjs/dist/ch.iife.min.js"></script>

if (Ch.isFunction(variable)) {
  //variable is a function
}

if (!Ch.isArray(variable)) {
  //variable is not an array
}
