constructor

• new ThenablePromise<T>(promise: Promise<T>): ThenablePromise<T>

  Type Parameters

  • T

  Parameters

  • promise: Promise<T>

  Returns ThenablePromise<T>

Readonly[toStringTag]

catch

• catch<TResult = never>(
      onrejected?: null | ((reason: any) => TResult | PromiseLike<TResult>),
  ): Promise<T | TResult>

  Attaches a callback for only the rejection of the Promise.

  Type Parameters

  • TResult = never

  Parameters

  • Optionalonrejected: null | ((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?: 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.

  Parameters

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

  Returns Promise<T>

  A Promise for the completion of the callback.

then

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

    The callback to execute when the Promise is resolved.

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

    The callback to execute when the Promise is rejected.

  Returns ThenablePromise<TResult1 | TResult2>

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

• thenCall(callback?: (err: any, value: undefined | T) => any): ThenablePromise<T>

  Parameters
