+Tiny module to clone an array of objects
+
+## Install
+
+```
+$ npm i clone-array-objects
+```
+
+## Usage
+
+This module helps us to get cloned array of objects
+
+```js
+const cloneArrayObjects = require('clone-array-objects');
+let users = [{ id: 1, username: 'bret' }, { id: 2, username: 'samantha' }];
+
+// Clone this users array
+let clonedUsers = cloneArrayObjects(users);
+console.log(clonedUsers);
+//=> [{ id: 1, username: 'bret' }, { id: 2, username: 'samantha' }];
+
+// Let us modify one of the object key value in the actual users array
+users[1].username = 'ava';
+
+// So, actual users array has been updated now
+console.log(users);
+//=> [{ id: 1, username: 'bret' }, { id: 2, username: 'ava' }];
+
+// But, the cloned users array is still the same
+console.log(clonedUsers);
+//=> [{ id: 1, username: 'bret' }, { id: 2, username: 'samantha' }];
+```
+
+## API
+
+### cloneArrayObjects(arrayInput)
+
+#### arrayInput
+
+Type: `Array`<br>
+Default: `[]`
