-1. Create a json-formatted text file called `quotes.json` containing 10 quotes, you can find lots of these on websites such as [brainyquotes](https://www.brainyquote.com/topics/inspirational). Each quote should include the quote and the author.
-2. Create a callback function that uses the [`fs.readfile()`](https://nodejs.org/api/fs.html#fs_fs_readfile_path_options_callback) function to read the contents of the file and display the quotes (but not the authors) in the terminal window.

 #### 2.3.1 ECMA6 Object Destructuring
 
 In ECMA6 is is possible to extract multiple pieces of data into separate variables by destructuring using an _object pattern_. This is syntactically similar to creating object literals (see the example below).
