 # Flatten Object
 
 > Flatten an object.
 
 <section class="usage">
 
 ## Usage
 
 ```javascript
 var flattenObject = require( '@stdlib/utils/flatten-object' );
 ```
 
 <a name="flatten-object"></a>
 
 #### flattenObject( obj\[, options] )
 
 Flattens an `object`.
 
 ```javascript
 var obj = {
     'a': {
         'b': {
             'c': 'd'
         }
     }
 };
 
 var out = flattenObject( obj );
 // returns { 'a.b.c': 'd' }
 ```
 
 The function accepts the following `options`:
 
 -   **depth**: maximum depth to flatten.
 -   **copy**: `boolean` indicating whether to deep [copy][@stdlib/utils/copy] property values. Default: `false`.
 -   **delimiter**: key path delimiter. Default: `'.'`.
 -   **flattenArrays**: `boolean` indicating whether to flatten `arrays`. Default: `false`.
 
 To flatten to a specified depth, set the `depth` option.
 
 ```javascript
 var obj = {
     'a': {
         'b': {
             'c': 'd'
         }
     }
 };
 
 var out = flattenObject( obj, {
     'depth': 1
 });
 // returns { 'a.b': {'c': 'd'} }
 
 var bool = ( obj.a.b === out['a.b'] );
 // returns true
 ```
 
 To deep [copy][@stdlib/utils/copy] property values, set the `copy` option to `true`.
 
 ```javascript
 var obj = {
     'a': {
         'b': {
             'c': 'd'
         }
     }
 };
 
 var out = flattenObject( obj, {
     'depth': 1,
     'copy': true
 });
 // returns { 'a.b': { 'c': 'd' } }
 
 var bool = ( obj.a.b === out['a.b'] );
 // returns false
 ```
 
 To specify a custom key path delimiter, set the `delimiter` option.
 
 ```javascript
 var obj = {
     'a': {
         'b': {
             'c': 'd'
         }
     }
 };
 
 var out = flattenObject( obj, {
     'delimiter': '-|-'
 });
 // returns { 'a-|-b-|-c': 'd' }
 ```
 
 By default, the function does **not** flatten `arrays`. To flatten `arrays`, set the `flattenArrays` option to `true`.
 
 ```javascript
 var obj = {
     'a': {
         'b': [ 1, 2, 3 ]
     }
 };
 
 var out = flattenObject( obj, {
     'flattenArrays': true
 });
 // returns { 'a.b.0': 1, 'a.b.1': 2, 'a.b.2': 3 }
 ```
 
 #### flattenObject.factory( options )
 
 Returns a `function` to flatten an `object`.
 
 ```javascript
 var flatten = flattenObject.factory({
     'delimiter': '|',
     'flattenArrays': true
 });
 
 var obj = {
     'a': {
         'b': {
             'c': 'd'
         }
     }
 };
 
 var out = flatten( obj );
 // returns { 'a|b|c': 'd' }
 
 obj = {
     'a': {
         'b': [ 1, 2, 3 ]
     }
 };
 out = flatten( obj );
 // returns { 'a|b|0': 1, 'a|b|1': 2, 'a|b|2': 3 }
 ```
 
 The function accepts the same `options` as [`flattenObject()`](#flatten-object).
