[toStringTag]: string

reject

reject: ((reason?: any) => void)

Rejects the Deferred

resolve

resolve: ((value?: T | PromiseLike<T>) => void)

Resolves the Deferred to a value T

Methods

catch

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

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

    Type Parameters

    • TResult = never

    Parameters

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

      The callback to execute when the Promise is rejected.

    Returns Promise<T | TResult>

    A Promise for the completion of the callback.

finally

  • finally(onfinally?): 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.

    Parameters

    • Optionalonfinally: (() => void)

      The callback to execute when the Promise is settled (fulfilled or rejected).

        • (): void

        • Returns void

    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

    Returns Promise<TResult1 | TResult2>

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