Interface PromiseLike<T>

then

• then<TResult1, TResult2>(onfulfilled?: ((value: T) => TResult1 | <internal>.PromiseLike<TResult1>), onrejected?: ((reason: any) => TResult2 | <internal>.PromiseLike<TResult2>)): <internal>.PromiseLike<TResult1 | TResult2>

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

  Type Parameters

  • TResult1 = T

  • TResult2 = never

  Parameters

  • Optional onfulfilled: ((value: T) => TResult1 | <internal>.PromiseLike<TResult1>)

    The callback to execute when the Promise is resolved.

    • • (value: T): TResult1 | <internal>.PromiseLike<TResult1>

      • Parameters

        • value: T

        Returns TResult1 | <internal>.PromiseLike<TResult1>

  • Optional onrejected: ((reason: any) => TResult2 | <internal>.PromiseLike<TResult2>)

    The callback to execute when the Promise is rejected.

    • • (reason: any): TResult2 | <internal>.PromiseLike<TResult2>

      • Parameters

        • reason: any

        Returns TResult2 | <internal>.PromiseLike<TResult2>

  Returns <internal>.PromiseLike<TResult1 | TResult2>

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