tour: Goroutine inconsistent output

[myerspliers]

Context: https://go.dev/tour/concurrency/1

Looking at the code, I would expect the output to have "hello" and "world" each printed five times. Most of the time it does, but sometimes "world" is only printed 4 times. I'm guessing the goroutine ends as soon as main exits, before "world" can print the last time, or something like that.

This behavior should be explained, or the example code should be changed so this doesn't happen.

I assume the browser doesn't matter for the "tour", but I saw this in both Firefox and Chrome.
