Background
From my experience introducing Go to development teams, I’ve explored various methods to help individuals transition from Go enthusiasts to proficient Go system developers. Finding the most effective approach for go learning within a team environment is crucial for success.
What Didn’t Work
Certain strategies, while well-intentioned, proved less effective in fostering widespread go learning and adoption within teams.
Read the Book: A Deep Dive That Deters
One approach we initially tried was centered around “the blue book“. The plan was to discuss each chapter weekly, along with tackling the exercises.
While I deeply value this book for its comprehensive exploration of Go, its demanding nature became a barrier. The book’s thoroughness, though beneficial for deep understanding, translates to a slow and steady pace. This intensive approach to go learning didn’t resonate with everyone.
We observed that while a dedicated few diligently read the assigned chapters and completed exercises, a significant portion of the team struggled to keep up. The commitment level required for this method of go learning proved to be too high for broader team adoption.
Solve Problems: Katas Lack Structure for Comprehensive Learning
Using katas seemed like a fun, hands-on way to learn. However, katas often present a limited scope for language exploration. For instance, you’re unlikely to delve into advanced concepts like goroutines when solving a typical kata. This makes katas less ideal for comprehensive go learning.
Another challenge arose from varying levels of engagement. Some individuals progressed much faster in their go learning than others. When these advanced learners showcased their solutions, they often introduced language features that were unfamiliar to the rest of the team, creating confusion and hindering collective go learning.
Ultimately, this approach made the go learning experience feel unstructured and ad hoc. The lack of a systematic progression made it difficult for everyone to stay aligned and build a shared understanding of Go.
What Did Work
The most impactful method for team-based go learning was a gradual introduction to the language’s fundamentals. This involved working through “go by example” together, exploring concepts with practical examples, and engaging in group discussions. This interactive approach proved far more effective than passively assigning chapters for homework in our go learning initiative.
Over time, the team developed a solid grasp of Go’s syntax and core concepts – the essential grammar of the language. This strong foundation then enabled us to move forward and start building more complex systems. This structured approach to go learning was key to our team’s progress.
This process mirrors the importance of practicing scales when learning guitar. No matter how much natural talent you possess, mastering the fundamentals and mechanics is essential for creating good music. Similarly, a strong foundation in Go’s fundamentals is crucial for effective go learning and building robust software.
What Works for Me
When I personally embark on go learning a new programming language, I usually start by experimenting in a REPL (Read-Eval-Print Loop). However, I eventually crave more structure for effective go learning.
My preferred method involves exploring concepts and then solidifying my understanding through tests. Writing tests serves two crucial purposes in my go learning process: it verifies the correctness of the code I write and acts as documentation for the features I’ve learned. This active approach to go learning ensures deeper comprehension and retention.
Drawing from my experience facilitating team go learning and my personal learning style, I aim to create a resource that benefits other teams. The goal is to facilitate go learning by focusing on fundamental concepts through small, test-driven exercises. This approach allows developers to leverage their existing software design skills and confidently build exceptional systems in Go, grounded in solid go learning principles.
