catch

• catch<TResult>(onRejected?): Promise<T | TResult>

• Attaches a callback for only the rejection of the Promise.

  Type Parameters

  • TResult = never

  Parameters

  • OptionalonRejected: null | ((reason: unknown) => TResult | PromiseLike<TResult>)

  Returns Promise<T | TResult>

  A Promise for the completion of the callback.

finally

  Returns Promise<T>

  A Promise for the completion of the callback.

then

• then<TResult1, TResult2>(onFulfilled?, onRejected?): Promise<TResult1 | TResult2>

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

  Type Parameters

  • TResult1 = T
  • TResult2 = never

  Parameters

  • OptionalonFulfilled: null | ((value: T) => TResult1 | PromiseLike<TResult1>)
  • OptionalonRejected: null | ((reason: unknown) => TResult2 | PromiseLike<TResult2>)

  Returns Promise<TResult1 | TResult2>

  A Promise for the completion of which ever callback is executed.
