## Day 5
## Day 5: `MediaQuery`, `prefersReducedMotion` and `createSubscriber`

Coming soon!
It's a three-in-one kind of day. `new MediaQuery(...)` gives you an object with a reactive `current` property that's true when the media query matches. `prefersReducedMotion` is an instance of `MediaQuery` that matches if the user has expressed a [preference for reduced motion](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-motion), helping you build accessible apps. Under the hood, both are using the `createSubscriber` mechanism, which gives you an easy way to set up event listeners when a value is read inside an effect.
