 ## Why
 
 In the past few years, async implementations are on the rise. Canceling promises is an important part of working with async code. For example, a very common pattern is for a user task to be canceled or interrupted with the need to compute the latest value. However a good solution for cancelation doesn't exist (see [Alternatives](#alternatives) section for explanation). In this new async world `p-signal` can help.
