    I have a quibble about this statement about 1-based indices

    When a baby completes its first roundtrip around the Sun, they’re one year old, not zero years old.

    Counting our ages is one instance in which we tend to start counting at 0 (like C) rather than 1 (like Lua) a newborn baby is 0 years old. We don’t phrase it that way, but they are a year away from being one year old, so they must be 0.
