Created August 8, 2018 18:37
Mixin for custom elements to easily declare properties.
const rxUpper = /([A-Z])/g
const observersMap = /** @type {WeakMap<any, {[x: string]: (function(string=): void)}>} */ (new WeakMap())
/**
* Mixin that provides a mechanism to declare properties and render when they change.
* It uses type constructors (String, Boolean, Number, Object, Function and Symbol) to check type validity.
* Set the type to undefined if you don't care about it.
* Properties of type String, Boolean and Number are automatically reflected to attributes.
* Make sure to call super.connectedCallback() if you are overriding the method.
