10 Most Common Pitfalls
1. Ignoring Error Handling
Go encourages explicit error handling. Ignoring errors can lead to unexpected behavior and bugs.
2. Using Global Variables
Global variables can lead to race conditions and make the code harder to test and maintain.
3. Improper Use of Goroutines
Creating too many goroutines without proper synchronization can lead to resource exhaustion and race conditions.
4. Misusing Channels
Improper use of channels, such as forgetting to close them or using them for inappropriate tasks, can cause deadlocks and memory leaks.
5. Inefficient String Concatenation
Using the + operator for string concatenation in loops can be inefficient. Use strings.Builder instead.
6. Ignoring Context
Not using context.Context for managing timeouts and cancellations can lead to resource leaks and unresponsive applications.
7. Poor Package Organization
Improper package organization can make the codebase difficult to navigate and maintain. Follow Go's conventions for package structure.
8. Overusing Interfaces
Defining interfaces prematurely or using them excessively can lead to unnecessary complexity. Define interfaces only when needed.
9. Not Using defer Properly
Misusing defer can lead to resource leaks. Ensure that defer is used to release resources like files and locks.
10. Ignoring Go's Concurrency Model
Not understanding Go's concurrency model can lead to inefficient and incorrect use of goroutines and channels. Learn and apply Go's concurrency patterns correctly.
