Javascript

Context

Your job is to write a command-line interface in Node.js. This program has to filter a list of elements containing a pattern.

In the following file data.js, there are Countries containing Peoples containing Animals.

Sample of running the command and the expected output:

# Only animals containing `ry` are displayed. The order should be kept intact

$ node app.js --filter=ry
[
   { name: 'Satanwi',
     people:
      [ { name: 'Elmer Kinoshita',
          animals:
           [ { name: 'Wrysel' },
        { name: 'Cora Howell',
          animals:
           [ { name: 'Rrya' },
             { name: 'Pronryorn' } ] },
        { name: 'Anthony Bruno',
          animals:
           [ { name: 'Caryxcal' },
             { name: 'Tryantula' },
             { name: 'Oryx' } ] } ] } ]
...
]

Bonus: As a bonus point, the next goal is to count People and Animals by adding the count of children in the name, eg. Satanwi [2].

Example:

node app.js --count
[
  { name: 'Satanwi [1]',
     people:
      [ { name: 'Elmer Kinoshita [1]',
          animals:
           [ { name: 'Wrysel' },
        { name: 'Cora Howell [2]',
          animals:
           [ { name: 'Rrya' },
             { name: 'Pronryorn' } ] },
        { name: 'Anthony Bruno [3]',
          animals:
           [ { name: 'Caryxcal' },
             { name: 'Tryantula' },
             { name: 'Oryx' } ] } ] } ]
...
]
