Let's write a simple NodeJS script that:

• Reads in up to 20 dates in the format "YYYY/MM/DD" from argv
• For each date, calculates how many days since that date have passed
• Creates a list of keys:value pairs that store date:days-since-date
• Outputs this as JSON to a file on the file system

Let's write a simple NodeJS script that:

• Starts up a simple HTTP server with one GET route called "/scrape"
  • This route takes in a URL and a particular HTML tag to look for and count
  • This route returns a simple object with the number of times that tag appears on a webpage
