## README

# jun-utils

前端通用工具函数库：校验、数据转换、浮点数运算、树结构操作等 9 个模块，提供 ES module 与 UMD 两种产物。

## Installation

Install with npm:

```bash
npm install --save-dev jun-utils
```

Install with yarn:

```bash
yarn add jun-utils --dev
```

## 浏览器支持

面向现代浏览器（Chrome 69+ / Safari 12+ / Firefox 62+ / Edge 79+，2018-09 起的全量版本），不支持 IE。

- `dist`【UMD】：`Number.isFinite` 等内建已由构建链内置 core-js@2 兜底
- `lib`【ESM】：不做 polyfill，需运行环境或消费方 polyfill 方案支持 ES2019 内建【如 `Array.prototype.flatMap`】

## Usage

ES6 module:

```JavaScript
import { check } from 'jun-utils'; // import check from 'jun-utils/lib/check';

// 手机号码校验
check.cellphone('13456789012'); // true
```

Script:

```html
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>jun-utils</title>
  <script src="jun-utils.min.js"></script>
</head>
<body>
  <script type="text/javascript">
    junUtils.check.cellphone('13456789012'); // true
  </script>
</body>
</html>
```
