I've been deceiving you all. I had you believe that Svelte was a UI framework — unlike React and Vue etc, because it shifts work out of the client and into the compiler, but a framework nonetheless.

But that's not exactly accurate. In my defense, I didn't realise it myself until very recently. But with Svelte 3 around the corner, it's time to come clean about what Svelte really is.

Svelte is a language.

Specifically, Svelte is an attempt to answer a question that many people have asked, and a few have answered: what would it look like if we had a language for describing reactive user interfaces?

A few projects that have answered this question:

Algebraic Effects in JavaScript part 4 - Implementing Algebraic Effects and Handlers

This is the final part of a series about Algebraic Effects and Handlers.

Part 1 : continuations and control transfer
Part 2 : Capturing continuations with Generators
Part 3 : Delimited continuations
Part 4 : Implementing Algebraic Effects and handlers

So we've come to the core topic. The reality is that we've already covered most of it in the previous parts. Especially, in the third part, where we saw delimited continuations at work.

Need

Convert .mov/.MP4 to .gif

Reason

As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.

This is not limited to developer, anyone has this need can use this method to convert the files.

I'd got rid of action types and I'd have only actions (action creators). No strings, the function (reference) is used later for comparisons.

export const addTodo = (id, title) => ({ id, title });
export const removeTodo = id => ({ id });
actions({ addTodo, removeTodo }); // Connect it to actions.addTodo & actions.removeTodo.

That's it. They define what your app can do.

	at the moment as I'm upgrading a 2D game, but will hopefully have more to add for 3D afterward.
