Flagger

Instructions

Create a function called flags that receives an object and outputs the specific aliases and descriptions from the properties of that object.

The help flag:

• Should be present in the output by default.
• When not present in the input, it should output the description of all flags. But when present it can specify the flags that you want to see the description of. (ex: help: ['divide'])

Example:

{
  multiply: 'multiply the values',
  divide: 'divides the values',
  help: ['divide']
}

and outputs :

{
  alias: { h: 'help', m: 'multiply', d: 'divide'}
  description: '-d, --divide: divides the values',
}
