• Clean launch, good luck!

• Are reactive updates based on deep equality or reference equality?

• I love the minimalist approach here. Using Proxies for state management without the heavy overhead of large frameworks is really elegant. Keeping it under 80 lines is impressive. Great work!

• I’m curious to know what performance looks like. In the recesses of my memory is the belief that proxies are not good for performance but I have no idea if that’s well founded (or maybe once was but isn’t any more).

  It’s a very smart idea though, I like it.

• Proposed variant optimised for human readaiblity...

  ```js import mador from "mador"; const [read, write] = mador({ count: 1 }); read(".counter", ctx => ctx.el.textContent = ctx.count); write(".increment", "click", ctx => ctx.count++); write(ctx => ctx.count = 0); ```

  ## Read

  Dependencies are detected automatically when the read function is run during initiation.

  ```js read(".counter", ctx => ctx.el.textContent = `Count: ${ctx.count}`); ```

  ## Write

  Immediate:

  ```js write(ctx => ctx.count++); ```

  Event-triggered:

  ```js write(".increment", "click", ctx => ctx.count++); ```

  Event writes expose `ctx.el` and `ctx.event`.

• There are many standalone plug-n-play implementations of the signal primitive in JS. To name a few: preact/signals, vue reactivity, etc, there's even a TC39 proposal for a lang feature. Is this meant to stand out by doing things differently or reinvent them?

• The syntax looks a bit too verbose for me. And function names like "read" and "write" are confusing too, given that "read" function isn't made for reading values. Cannot we use a single function for binding, like this (and name it "bind")?

      let counter = proxy({ count: 0 });
      bind('.counter', (el) => el.textContent = counter.count);
      counter.count++; // Queues DOM update
  

  Also,

  > Mador is distributed as an ES module.

  This means it cannot be used on a page opened from disk, and the user needs to set up a HTTP server which is time-consuming and distracting. And you cannot distribute an app as as HTML file.
