Usage

Simple utils for JavaScript: type checkers, regex patterns, and environment support flags.

helping-js is vanilla JavaScript with no external dependencies. It supports ES5 (CommonJS) and ES modules, and works in Node and browsers.

Installation

npm install helping-js --save

yarn add helping-js

Usage

1. You can import in your js file es6 (modules,vue,react,...)

import { isString } from 'helping-js/core/types'

console.log(isString('test')) // true
console.log(isString(true)) // false

2. You can import in your js file es5 (nodejs)

var { isString } = require('helping-js/core/types')

console.log(isString('test')) // true
console.log(isString(true)) // false

3. You can use from CDN (ESM only). For production, pin a version: https://unpkg.com/helping-js@2/core/types.js

import { isString } from 'https://unpkg.com/helping-js/core/types.js'

console.log(isString('test')) // true
console.log(isString(true)) // false

4. TypeScript: The package ships with declaration files (.d.ts). Import from helping-js/core/types (or other subpaths) and you get full type checking.
