+### 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(', ');
+};
+```
+
+```js
+formatDuration(1001); // "1 second, 1 millisecond"
+formatDuration(343250555); // "3 days, 23 hours, 20 minutes, 50 seconds, 555 milliseconds"
