Golang by Example

What's Next?

We have covered a lot of ground in this Golang by Example series. You have learned about the basics of Go, including its syntax, data types, control structures, and functions. You have also explored more advanced topics such as concurrency, error handling, and testing.

To be successful in Go, it is important to practice and build real-world applications. Here are some suggestions for what to do next:

Build a project: Choose a project that interests you and start building it using Go. This could be a web application, a command-line tool, or anything else you can think of. I find that building a project is the best way to learn a new language. Codecrafters is a great resource for building projects in Go. It provides a series of challenges that you can solve using Go, and it also has a community where you can ask questions and get help.
Deepen your knowledge in data structures and algorithms: Understanding data structures and algorithms is crucial for writing efficient code. Consider studying common data structures (e.g., arrays, linked lists, trees) and algorithms (e.g., sorting, searching) in Go. Since I am a visual learner, I like this website to learn about data structures and algorithms: VisuAlgo.
SQL and databases: Learn how to interact with databases using Go. Familiarize yourself with SQL and how to use Go's database/sql package to perform CRUD operations. This is a good book from O'Reilly that covers this topic: PostgreSQL: Up and Running.
Monitoring and logging: Explore how to monitor and log your Go applications. Learn about popular libraries like Prometheus or SigNoz for monitoring. Watch this video to learn how to monitor your Go applications: Monitoring Go Applications with Prometheus or How to Set Up Prometheus & Grafana: Monitoring an API with Golang.
