100 Go Mistakes and How to Avoid Them Avoid using global variables: They can lead to unexpected behavior and make it difficult to track down errors. Use type assertions carefully: They can introduce runtime errors if the type conversion is incorrect. Check for errors when using channels: Use the err channel to handle errors gracefully. Avoid using nil values: They can lead to unexpected behavior and make it difficult to debug. Use defer to clean up resources: This ensures that resources are always released, even if an error occurs. Use recover to handle panics: This allows you to catch and handle panics gracefully. Use sync.Mutex to protect shared data: This prevents data races and ensures that data is accessed safely. Use sync.WaitGroup to wait for goroutines: This ensures that all goroutines have finished before proceeding. Use context.Context to cancel operations: This allows you to cancel operations that are taking too long or are no longer needed. Use testing package for unit testing: This helps to ensure that your code is working as expected.
