Part 3: Error Handling & Testing

Go's approach to errors is unique; doing it wrong leads to unreadable code.

• Mistake #48: Panic for Normal Errors.
  • The Issue: Using panic for error handling (like in Java or Python exceptions) instead of returning error values.
  • The Fix: Only use panic for unrecoverable states (e.g., during startup initialization).
• Mistake #60: Ignoring Error Wrapping.
  • The Issue: Returning errors without adding context, making debugging difficult.
  • The Fix: Use fmt.Errorf("operation failed: %w", err) to wrap errors while preserving the original cause.

4. Mixing up sync.Mutex with Pointers (Mistake #76)

Copying a struct containing a sync.Mutex creates a copy of the mutex, breaking the lock. "100 Go Mistakes and How to Avoid Them"

Quick Start: 3 Mistakes to Avoid Today

// ❌ Mistake #1: Loop variable capture
for i := 0; i < 3; i++ 
    go func()  fmt.Println(i) () // prints 3,3,3
// ✅ Fix: Pass as argument
for i := 0; i < 3; i++ 
go func(i int)  fmt.Println(i) (i)

// ❌ Mistake #2: Nil interface check
var p *int = nil
var i interface{} = p
fmt.Println(i == nil) // false!
// ✅ Fix: Check underlying type/value
fmt.Println(p == nil) // true Common pitfalls in error handling, such as ignoring
// ❌ Mistake #3: Closing HTTP response body incorrectly
resp, _ := http.Get(url)
defer resp.Body.Close() // may leak if resp is nil
// ✅ Fix: Check nil first
if resp != nil 
defer resp.Body.Close()
