The fork/join model runs independent subtasks in parallel, collects their partial results, and merges them before the program continues. In Go, the fork creates goroutines, while the join consumes a shared results channel after all work completes. section 10.2.2
A practical example scans a directory for Go files and finds the file containing the deepest nested code block. Each file is processed independently; the final step selects the greatest nesting depth. section 10.2.2
Deepest nested source file
Running the scanner can produce: “longestwords.go has the deepest nested code block of 6.”
