Create a pipeline that reads text files, finds the number of occurrences of a given phrase in each text file, and calculates the total number of occurrences of the phrase in all files.
Create a pipeline for calculating the sum of the squares of all of the natural numbers in a given range.
Remove the
time.Sleep(1 * time.Second)statement from thesimple.goprogram and see what happens. Why does this happen?Modify the Go code of
pipeline.goin order to create a pipeline with five functions and the appropriate number of channels.Modify the Go code of
pipeline.goin order to find out what will happen when you forget to close theoutchannel of thefirst()function.

Overview of this book
<p>Often referred to as Golang (albeit wrongly), the Go programming language is really making strides thanks to some masterclass developments, architected by the greatest programming minds. Shopify CEO Tobias Lutke has been recently quoted as saying “Go will be the server language of the future.” Go programmers are in high demand, but - more controversially - Go takes the stage where C and Unix programmers previously led the way.</p>
<p>The growth of the Go language has seen it become the means by which systems, networking, web, and cloud applications are implemented. If you’re a Go programmer, you’ll already know some Go syntax and will have written some small projects. However, most Go programmers face the difficulty of having to integrate their Golang skills with production code. With Mastering Go, the author shows you just how to tackle this problem. You'll benefit by mastering the use of the libraries and utilize its features, speed, and efficiency for which the Go ecology is justly famous.</p>
<p>Offering a compendium of Go, the book begins with an account of how Go has been implemented. You'll also benefit from an in-depth account of concurrency and systems and network programming imperative for modern-day native cloud development through the course of the book.</p>
