Study on using node.JS filesystem

https://nodejs.org/api/fs.html

1) Create a File - userInputToFile.js - makeNewFile();

* Using input from terminal readline prompts, this file will accomplish three things:

    --- Stores File Name input
    --- Store File content input
    --- Creates a new file with the stored information

* Node.js modules used:
   
    --- rl.question();
    --- fs.writeFile();

2) Read a File - readFile.js - readFile();

* Using input from terminal readline prompts, this file will accomplish two things:

    --- Stores input for file name
    --- Displays the inner text of the file

* Node.js modules used:

    --- rl.question();
    --- fs.readFile();

3) Copy a File - copyFile.js - copyFile();

* Using input from terminal readline prompts, this file will accomplish three things:

    --- Stores input for original file name
    --- Stores input for new file name
    --- Creates a new file, duplicating the contents of the original file

* Node.js modules used:

    --- rl.question();
    --- fs.copyFile();

4) Update a File - updateFile.js - updateFile();

* Using input from terminal readline prompts, this file will accomplish two things:

    --- Stores input for file name
    --- Appends updated content to the end of the file

* Node.js modules used:

    --- rl.question();
    --- fs.appendFile();        

5) Delete a File - unlinkFile.js - deleteFile();

* Using input from terminal readline prompts, this file will accomplish two things:

    --- Stores input for file name
    --- Delete the file 

* Node.js modules used:

    --- rl.question();
    --- fs.unlink();
