    The callback to execute when the Promise is rejected.

  Returns Promise<void | TResult>

  A Promise for the completion of the callback.

finally

• finally(onfinally?: () => void): Promise<void>

  Returns Promise<void>

  A Promise for the completion of the callback.

then

• then<TResult1 = void, TResult2 = never>(
      onfulfilled?: (value: void) => TResult1 | PromiseLike<TResult1>,
      onrejected?: (reason: any) => TResult2 | PromiseLike<TResult2>,
  ): Promise<TResult1 | TResult2>

  Attaches callbacks for the resolution and/or rejection of the Promise.

  Type Parameters

  • TResult1 = void
  • TResult2 = never

  Parameters

  • Optionalonfulfilled: (value: void) => TResult1 | PromiseLike<TResult1>

    The callback to execute when the Promise is resolved.
  • Optionalonrejected: (reason: any) => TResult2 | PromiseLike<TResult2>

    The callback to execute when the Promise is rejected.

  Returns Promise<TResult1 | TResult2>
