Go (also known as Golang) is one of the most popular languages today and is a key part of many enterprise tech stacks. Because Go's memory management architecture makes concurrency easier, many developers prefer it over traditional languages.

In this course, you will learn the core constructs and techniques of Go as well as advanced concepts of the language. In particular, you’ll learn how to program efficiently by becoming aware of the pitfalls and patterns that are commonly encountered in Go and by building your own applications.

Once you’ve completed this course, you will be able to write concurrent programs and improve the performance of existing ones, thus creating a more robust experience for everyone. Concurrency is in high demand today since it enables developers to reduce execution time of applications significantly, and Golang provides a very rich support for achieving this.

Concurrency in Go

Consider a classic livelock scenario in which a husband and wife named Alice and Bob attempt to eat soup but only have one spoon between them. Each spouse is overly courteous and will pass the spoon to the other if the other hasn’t eaten yet.

Use the steps below to create this livelock scenario in Golang:

* Create a function that creates a lock on resource `x` (a spoon in this case), does some processing (use the `time.Sleep` function for the time being), and before using the resource, checks if it is required by the other process (the spouse in this case).

* If the spouse is hungry, leave the lock on the resource (the spoon) and start demanding the resources again. Launch the two goroutines that are passing `WaitGroup` and the resource’s pointer reference.

* For locking and unlocking, use the provided code snippet.

* For the output, try to print something that indicates that spouse one is picking up resource `x`, checking if the other spouse is hungry, and leaving the resource.
