Requirements

  • allow the user to supply a CLI argument containing a comma-separated list of tags
    • if no argument is given, load tags.txt to get an array of tags.
  • for each of these tags, find out how many times that tag appears within the objects in data/*.json (note: objects can be nested).
  • final output should be formatted like this (sorted by most popular tag first):
pizza     15
spoon     2
umbrella  0
cats      0
  • cache the result so that subsequent runs can return the result immediately without needing to process the files.
  • use only core modules
  • use the asynchronous variants of the file IO functions (eg. use fs.readFile not fs.readFileSync).
  • if any of the data files contain invalid JSON, log the error with console.error and continue, ignoring that file.
  • you can use any version of node, however your solution must use plain callbacks rather than promises.
