Variable MaybePromise

Type declaration

• isThenable: (<T>(value) => value is PromiseLike<T>)

  • • <T>(value): value is PromiseLike<T>

    • Returns if a value is like a thenable.

      Type Parameters

      • T

      Parameters

      • value: MaybePromise<T>

      Returns value is PromiseLike<T>

• map: (<T, R, R2>(value, mapValue, mapError?) => MaybePromise<R | R2>)

  • • <T, R, R2>(value, mapValue, mapError?): MaybePromise<R | R2>

    • Transforms a value or promise with a maybe-async value mapper (and optionally error mapper).

      Type Parameters

      • T

      • R = T

      • R2 = never

      Parameters

      • value: MaybePromise<T>
