Typical C++ dev schizophrenia. In one thread complain about Node and its death-by-a-thousand-packages, then suggest the same in another.

So it is NOT built-in and the code example shown above is dishonest - @SuperV1234 compares how "lean" two languages are but conveniently hides half of the code in their preferred language to make it seem simpler that it actually is, as otherwise it would look bad in the comparison!
