+
+Listen for changes. Like an event emitter that only emits a single event type. Really tiny.
+
+I extracted this from Redux's `createStore()` because I found it to be useful in other contexts. Use it where you want the most minimal event subscription implementation possible.
+
+## Usage
+
+```js
+import { createChangeEmitter } from 'change-emitter'
+
+const emitter = createChangeEmitter()
+
+// Called `listen` instead of `subscribe` to avoid confusion with observable spec
+const unlisten = emitter.listen((...args) => {
+  console.log(args)
+})
+
+emitter.emit(1, 2, 3) // logs `[1, 2, 3]`
+unlisten()
+emitter.emit(4, 5, 6) // doesn't log
+```
+
+## Larger example
+
+Here's a (partial) implementation of Redux's `createStore`:
+
+```js
+const createStore = (reducer, initialState) => {
+  let state = initialState
+  const emitter = createChangeEmitter()
+
+  function dispatch(action) {
+    state = reducer(state, action)
+    emitter.emit()
+    return action
+  }
+
+  function getState() {
+    return state
+  }
+
+  return {
+    dispatch,
+    getState,
+    subscribe: emitter.listen
+  }
+}
+```
