Excellent post, though for number 5 I'd note that using Set does indeed remove duplicates but only if the array is filled with primitive values.

In the case of an array being filled with objects, however...

const departureTimes = [{"departureTime": "07:00:00"}, {"departureTime": "07:00:00"}, {"departureTime": "13:05:00" }];
const unique = Array.from(new Set(departureTimes)); // [{"departureTime":"07:00:00"},{"departureTime":"07:00:00"},{"departureTime":"13:05:00"}]

A little overkill but In this case something like this could also work:

const unique = Array.from(new Set(departureTimes.map(x => JSON.stringify(x)))).map(x => JSON.parse(x)); // [{"departureTime":"07:00:00"},{"departureTime":"13:05:00"}]

I don't see how 14 and 16 are 'jurassic' versions. 18 is the latest.
Thanks for the update though

In production environments, either Active LTS (16) or Maintenance LTS (14) should be used.

Node 18 is not an LTS at all, it's the Current release, and it is not quite fit for production use until the 25th of october, when it will become Active LTS

It's all here: github.com/nodejs/release#release-...
