## ⏱️ Date
### formatDuration
Returns the human readable format of the given number of milliseconds.
Divide `ms` with the appropriate values to obtain the appropriate values for `day`, `hour`, `minute`, `second` and `millisecond`.
Use `Object.entries()` with `Array.filter()` to keep only non-zero values.
Use `Array.map()` to create the string for each value, pluralizing appropriately.
Use `String.join(', ')` to combine the values into a string.
```js
const formatDuration = ms => {
if (ms < 0) ms = -ms;
const time = {
day: Math.floor(ms / 86400000),
hour: Math.floor(ms / 3600000) % 24,
minute: Math.floor(ms / 60000) % 60,
second: Math.floor(ms / 1000) % 60,
millisecond: Math.floor(ms) % 1000
};
return Object.entries(time)
.filter(val => val[1] !== 0)
.map(val => val[1] + ' ' + (val[1] !== 1 ? val[0] + 's' : val[0]))
.join(', ');
};

### luhnCheck
Implementation of the [Luhn Algorithm](https://en.wikipedia.org/wiki/Luhn_algorithm) used to validate a variety of identification numbers, such as credit card numbers, IMEI numbers, National Provider Identifier numbers etc.
Use `String.split('')`, `Array.reverse()` and `Array.map()` in combination with `parseInt()` to obtain an array of digits.
Use `Array.splice(0,1)` to obtain the last digit.
Use `Array.reduce()` to implement the Luhn Algorithm.
Return `true` if `sum` is divisible by `10`, `false` otherwise.
```js
const luhnCheck = num => {
let arr = (num + '')
.split('')
.reverse()
.map(x => parseInt(x));
let lastDigit = arr.splice(0, 1)[0];
let sum = arr.reduce((acc, val, i) => (i % 2 !== 0 ? acc + val : acc + (val * 2) % 9 || 9), 0);
sum += lastDigit;
return sum % 10 === 0;
};
