There are some blocks of code that require a preamble, and an explanation of the code and its flow. Often you need to provide some broader context.

Sometimes, you get some code like Wolf found, which needs no explanation:

export function generateRandomId(): string {
    counter++;
    return 'id' + counter;
}

I mean, I guess that's a slightly better than this solution. Wolf found this because some code downstream was expecting random, unique IDs, and wasn't getting them.
