-> Map `visit` over an array of objects.
-
-## Install
-
-Install with [npm](https://www.npmjs.com/):
-
-```sh
-$ npm install --save map-visit
-```
-
-## Usage
-
-```js
-var mapVisit = require('map-visit');
-```
-
-## What does this do?
-
-**Assign/Merge/Extend vs. Visit**
-
-Let's say you want to add a `set` method to your application that will:
-
-* set key-value pairs on a `data` object
-* extend objects onto the `data` object
-* extend arrays of objects onto the data object
-
-**Example using `extend`**
-
-Here is one way to accomplish this using Lo-Dash's `extend` (comparable to `Object.assign`):
-
-```js
-var _ = require('lodash');
-
-var obj = {
- data: {},
- set: function (key, value) {
- if (Array.isArray(key)) {
- _.extend.apply(_, [obj.data].concat(key));
- } else if (typeof key === 'object') {
- _.extend(obj.data, key);
- } else {
- obj.data[key] = value;
- }
- }
-};
-
-obj.set('a', 'a');
-obj.set([{b: 'b'}, {c: 'c'}]);
-obj.set({d: {e: 'f'}});
-
-console.log(obj.data);
-//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }}
-```
-
-The above approach works fine for most use cases. However, **if you also want to emit an event** each time a property is added to the `data` object, or you want more control over what happens as the object is extended, a better approach would be to use `visit`.
-
-**Example using `visit`**
-
-In this approach:
-
-* when an array is passed to `set`, the `mapVisit` library calls the `set` method on each object in the array.
-* when an object is passed, `visit` calls `set` on each property in the object.
-
-As a result, the `data` event will be emitted every time a property is added to `data` (events are just an example, you can use this approach to perform any necessary logic every time the method is called).
-
-```js
-var mapVisit = require('map-visit');
-var visit = require('object-visit');
-
-var obj = {
- data: {},
- set: function (key, value) {
- if (Array.isArray(key)) {
- mapVisit(obj, 'set', key);
- } else if (typeof key === 'object') {
- visit(obj, 'set', key);
- } else {
- // simulate an event-emitter
- console.log('emit', key, value);
- obj.data[key] = value;
- }
- }
-};
-
-obj.set('a', 'a');
-obj.set([{b: 'b'}, {c: 'c'}]);
-obj.set({d: {e: 'f'}});
-obj.set({g: 'h', i: 'j', k: 'l'});
-
-console.log(obj.data);
-//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }, g: 'h', i: 'j', k: 'l'}
-
-// events would look something like:
-// emit a a
-// emit b b
-// emit c c
-// emit d { e: 'f' }
-// emit g h
-// emit i j
-// emit k l
-```
