Flagger

Instructions

Create a function called flags that receives an object and returns 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 return the description of all flags. But when present it specifies the descriptions of the flags that are passed to help. (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',
}
