Assuming single-threaded runtime behavior in production. Fix: test concurrency and consider race detector.
Understanding how the garbage collector (GC) and escape analysis work. Top 3 Common Mistakes You’ll Learn to Fix // Good practice go func() defer func() if r := recover(); r
Go has only 25 keywords, no inheritance, and a highly streamlined syntax. Yet, writing production-ready, highly concurrent Go applications requires a paradigm shift.
Slices in Go are backed by underlying arrays. Understanding how they reference memory is crucial for writing efficient code.
Appending to a slice that shares an underlying array with another slice can unexpectedly overwrite data in the original slice. 3. Standard Library Misuse
