Go is a popular language known for its simplicity. For developers who lack a deep knowledge of its features, it's a great time to pick up the Go language. The differences between Go and other popular programming languages can lead to hours of Google for the newer software engineer. Mastering these surprising, sometimes delightful, sometimes frustrating features can be the difference between time spent on debugging and time spent on deployment.

In this course, you will go deeper than an introductory book to learn the various features that make Go unique. You’ll learn how to protect against the bugs caused by poorly defined variables (and variable shadowing), how Go treats slicers and arrays similarly, and how to work with multidimensional datasets. You’ll also dive into memory handling, strings, loops, and goroutines.

This course will be most useful if you already have a basic understanding of Go and its syntax. By the end of the course, you’ll move from Go-familiar to Go-expert.

# Data races

A regular Go `map` isn't safe for concurrent access. Maps are often
used to share data between *goroutines*, but access to a `map` must
be synchronized through `sync.Mutex, sync.RWMutex`, some other
memory barrier, or coordinated with Go channels to prevent
concurrent access, with the following exception:

> **Note:** map access is unsafe only when updates are occurring. As long as all goroutines are only reading—looking up elements in the map, including iterating through it using a for ... range loop—and not changing the map by assigning to elements or doing deletions, it is safe for them to access the map concurrently without synchronization. See the [documentation](https://go.dev/doc/faq#atomic_maps):
