mutant/watch-event.js

Create observables and map them to DOM elements. Massively inspired by hyperscript and observ-*. No virtual dom, just direct observable bindings. Unnecessary garbage collection is avoided by using mutable objects instead of blasting immutable junk all ove

module.exports = function watchEvent (element, eventName, handler) {
    element.addEventListener(eventName, handler)
    return function unlisten () {
      element.removeEventListener(eventName, handler)
    }
