## Retry
失败自动重试，可用于 http 请求重试，或其他需要重试的逻辑
### Install
```sh
npm i @4a/retry
```
### Usage
```js
// ES6
import Retry from '@4a/retry'
// Nodejs
const Retry = require('@4a/retry')
```
### Example
```js
let i = 0
Retry.delay(300) // 可选调用 重试间隔300ms，默认300ms，单位ms
.max(10) // 可选调用 重试次数10，默认3次防止死循环
.when((result) => result !== 10) // 必须调用 重试条件，符合条件则重试，否则视为成功正常返回
.repeat(() => {
// 支持async函数，支持promise，返回Promise
i++
return i
})
.then((result) => {
console.log('result:', result)
})
.catch((err) => {
// 报错视为失败
// 最后一次重试如果依然报错，则抛出该错误
console.error('error:', err)
})
```
Simple
```js
let i = 0
Retry.when((result) => result !== 10)
.repeat(() => {
i++
return i
})
.then((result) => {
console.log('result:', result)
})
.catch((err) => {
console.error('error:', err)
})
```
Axios Request
```js
Retry.when((result) => result.data.code !== 0)
.repeat(() => axios(options))
.then((result) => {
console.log('result:', result)
})
.catch((err) => {
console.error('error:', err)
})
```
