Algebraic Effects in JavaScript part 1 - continuations and control transfer

This is the first post of a series about Algebraic Effects and Handlers.

There are 2 ways to approach this topic:

• Denotational: explain Algebraic Effects in terms of their meaning in mathematics/Category theory
• Operational: explain the mechanic of Algebraic Effects by showing how they operate under a chosen runtime environment

Both approaches are valuables and give different insights on the topic. However, not everyone (including me), has the prerequisites to grasp the concepts of Category theory and Abstract Algebra. On the other hand, the operational approach is accessible to a much wider audience of programmers even if it doesn't provide the full picture.

Service Workers Tips

Reloading a service worker

Reloading a page won't update/remove the previous version of its service worker. To make sure you're using the latest version of your service worker, make sure to check the "Update on reload" toggle in the "Application" ⭢ "Service Workers" section of the Chrome DevTools.

Simulate a network condition

To simulate a network condition (e.g.: offline, 3g, etc...) in a service worker on Chrome, uncheck the "Update on reload" toggle.
