* Turns an object whose values are action creators, into an object with the
|
|
* same keys, but with every function wrapped into a `dispatch` call so they
|
|
* may be invoked directly. This is just a convenience method, as you can call
|
|
* `store.dispatch(MyActionCreators.doSomething())` yourself just fine.
|
|
*
|
|
* For convenience, you can also pass a single function as the first argument,
|
|
* and get a function in return.
|
|
*
|
|
* @param {Function|Object} actionCreators An object whose values are action
|
|
* creator functions. One handy way to obtain it is to use ES6 `import * as`
|
|
* syntax. You may also pass a single function.
|
|
*
|
|
* @param {Function} dispatch The `dispatch` function available on your Redux
|
|
* store.
|
|
*
|
|
* @returns {Function|Object} The object mimicking the original object, but with
|
|
* every action creator wrapped into the `dispatch` call. If you passed a
|
|
* function as `actionCreators`, the return value will also be a single
|
|
* function.
