Let's create our own package manager

• Create a node program
• Check for the first process argument to be init
• If the first argument is init continue processing else end the program
• check if a file named package.json already exists, if it does exit the program
• Use readline to ask for 5 inputs
• Create a string that is a json object
• The key values should be the inputs you get from the user
• Save this json to a file called package.json

Bonus

• Don't hardcode 5 readline.question() s
• Don't using string concatenation or template literals
