function isEmitter(emitter) {
  if (!emitter) return false
  let check = ['on','emit']
  return check.reduce((acc,fn)=> acc && typeof emitter[fn] ==='function',true)
}

function isAsync(fn) {
  if (typeof fn !== 'function') return false
  return (isPromise(fn) || fn.constructor.name === 'AsyncFunction')
}
```
