There was a problem hiding this comment.
It be better to add a Parameter in the function instead declaring the variable . Like
go func(url string) {
resultChannel <- result{url, wc(url)}
}(url)Signed-off-by: Eduard Kaverinskyi <[email protected]>

The current version's tests didn't work for me at the end of the section. I propose a fix.
The exact wording or maybe even the implementation may be improved/modified, but I think this should be covered in the tutorial.
