Usage

- Please use npm/yarn install this package
`shell
npm i isbox --save

or

yarn i isbox --save
`
- import or require what you need
`javascript
// in node.js
const isbox = require('isbox')
isbox.isWindow(window)
// false
isbox.isWindow(null)
// false
isbox.isWindow('')
// false

// in frontend
import { isWindow } from 'isbox'

isWindow(window)
// true
isWindow(null)
// false
isWindow('')
// false
`

"is"

- Example 1: Base on call()ing constructor
- 方法一： 基本数据类型判断，基于构造类名判断

`javascript
import { is } from 'isbox'

is(123, 'Number')
// true
is(null, 'Null')
// true
is(null, 'Object')
// false
is([], 'Array')
// true
is([], 'Object')
// false
is('', 'String')
// true
is(new Set(), 'Set')
// true
`
- Example 2: Using constructor directly.
- 方法二： 通过判断constructor
`javascript
const arr = [1,2,3]
console.log(arr.constructor === Array)
// true
console.log(new Set().constructor === Set)
// true
`

"isServer"

- 判断当前环境是不是服务端
- Check if this is server side.
- type: Boolean
- value: true or false
`javascript
// 在Nodeh环境执行
// execute in Node env
console.log(isbox.isServer)
// true

// 在浏览器环境执行
// execute in Broswer env
console.log(isbox.isServer)
// false

`

"isClient"

- 判断当前环境是不是客户端，与isServer互相对立
- If current env is Client, is the opposite of isServer
- type: Boolean
- value: true or false
`javascript
// 在Nodeh环境执行
// execute in Node env
console.log(isbox.isClient)
// false

// 在浏览器环境执行
// execute in Broswer env
console.log(isbox.isClient)
// true

`

"isNumber"

`javascript
// in node.js
const isbox = require('isbox')
isbox.isNumber(NaN)
// true
isbox.isNumber(123)
// true
isbox.isNumber(null)
// false
isbox.isNumber('')
// false

import { isNumber } from 'isbox'

isNumber(123)
// true
isNumber(null)
// false
isNumber('')
// false
`

"isObject"

`javascript
import { isObject } from 'isbox'

isObject(123)
// false
isObject(null)
// true
isObject({a: 234})
// true
isObject('')
// false
`

"isEmpty"

`javascript
import { isEmpty } from 'isbox'

isEmpty(123)
// false
isEmpty({})
// true
isEmpty([])
// true
isEmpty('')
// true
