Function each

each<T>(values, iterator): Promise<void>
Iterate over an array, or a promise of an array, which contains promises (or a mix of promises and values) with the given iterator function with the signature (item, index) where item is the resolved value of a respective promise in the input array. Iteration happens serially. If any promise in the input array is rejected the returned promise is rejected as well.

If the iterator function returns a promise or a thenable, the result for the promise is awaited for before continuing with next iteration.
Type Parameters
- T
Parameters
- values: Iterable<T | PromiseLike<T>, any, any> | PromiseLike<Iterable<T | PromiseLike<T>, any, any>>
  The array of values to iterate over.
- iterator: ((item: T, index: number) => void | PromiseLike<void>)
  The iterator function to apply to each element.
  - - (item, index): void | PromiseLike<void>
    - Parameters
      item: T
      index: number
      Returns void | PromiseLike<void>
Returns Promise<void>
