Delimited Continuations are all you need

An advanced exploration of delimited continuations using TypeScript generators to manage complex asynchronous flow control.

This talk is about a concept called "Delimited Continuations". This is definitely a quite advanced topic that will test your knowledge of TypeScript generators (including async generators!). By using delimited continuations, developers can more easily manage asynchronous tasks and ensure that tasks are executed in a predictable and coordinated way. This gets you a more reliable and responsive app (with an improved user experience, too).
