# usage

```javascript

  function * foo () {

    yield (cb) => setTimeout(cb, 1000)

    console.log('done cb')

  }

  const run = require('run-duck-run')

  run(foo, (err) => {

    if (err) {

      console.error(err)

    } else {

      console.log('all good')

    }

  })()

  // done cb

```

```javascript

  function * foo () {

    yield new Promise((resolve, reject) => {

      setTimeout(resolve, 1000)

    })

    console.log('done promise')

  }

  const run = require('run-duck-run')

  run(foo, (err) => { })()

  // done promise

```

`yield supports thunks and promises.`

# Why?

If you find a pattern where error handling can all be done in one place....

When writing http routes, error handling is often performed in multiple places....

Check out [server-base](https://npm.im/server-base) for an example of using this module.
