      A Promise for the completion of the callback.

Readonlyfinally

finally: ((onfinally?: null | (() => void)) => Promise<T>)

Attaches a callback that is invoked when the Promise is settled (fulfilled or rejected). The resolved value cannot be modified from the callback.

Readonlythen

then: (<TResult1, TResult2>(onfulfilled?: null | ((value: T) => TResult1 | PromiseLike<TResult1>), onrejected?: null | ((reason: any) => TResult2 | PromiseLike<TResult2>)) => Promise<TResult1 | TResult2>)

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

    • <TResult1, TResult2>(onfulfilled?, onrejected?): Promise<TResult1 | TResult2>

    • Type Parameters

      • TResult1 = T
      • TResult2 = never

      Parameters

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

        The callback to execute when the Promise is resolved.

      • Optionalonrejected: null | ((reason: any) => TResult2 | PromiseLike<TResult2>)
