I’m sorry for the delay in writing. Last week I was under the weather. Let’s pick up our discussion of goroutines and errors. Last time, I talked about errgroup, which makes it easy to run an arbitrary number of goroutines, and gather the first error (if any) that one returns. But what if that error renders the rest of the goroutines obsolete? A very common case is that any error means that the rest of the processing becomes moot.
