time

Gets the times of a list from an array of roles

        ttl: '15 minutes'
    },
    {
        role: 'Specialist',

let candidates = [
    'Developer',
    'Administrator',
    'Designer'
];

time(roles, candidates);
/*
->
[
  { role: 'Developer', ttl: '15 minutes' },
  { role: 'Administrator', ttl: '1 years' },
  { role: 'Designer', ttl: '55 hours' }
]
*/

calc

Calculate time of multiple roles assigned to a user

import {calc} from 'role-calc';

// Roles with time
let roles = [
    {
        role: 'Developer',
        ttl: '15 minutes'
    },
    {
        role: 'Specialist',
        ttl: '2 hours'
    },

    {
        role: 'other'
    }

/*
time(roles, option, format)

- roles: array
- option: max, min, sum, average
- format(optional): milliseconds, seconds, minutes, hours, days, weeks, months, years
*/

calc(roles, 'sum'); // -> 533805 minutes
calc(roles, 'max', 'hours'); // -> 8766 hours
calc(roles, 'min', 'minutes'); // -> 15 minutes
