Refactor for clean code

what about PromiseLike entities?

[tanvirstreame]

Good point. I want to make this line more understandable. How about I change this to -

export function isPromise(value: any): value is Promise<any> {
  return value?.then instanceof Function;
}

or this -

export function isPromise(value: any): value is Promise<any> {
  return Boolean(value && value.then);
}
