Let's demo together!

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 demo together!

Let's write a simple NodeJS script that:

  • Starts up a simple HTTP server with one GET route called "/scrape"
