sync.OnceFunc vs init(): Lazy Initialization Done Right in Go

1. 1Use sync.OnceFunc to initialize functions lazily
2. 2Replace init() with sync.OnceValue for variable initialization
3. 3Test your code to ensure thread safety
4. 4Configure your tests to handle lazy initialization
5. 5Apply sync.OnceFunc and OnceValue to existing codebases

Go developers and software engineers can benefit from using sync.OnceFunc and OnceValue to ensure thread-safe and testable lazy initialization, improving overall code quality and reliability

💡 sync.OnceFunc and OnceValue provide a safer and more testable alternative to init() for lazy initialization in Go

💡 Use sync.OnceFunc and OnceValue in Go for thread-safe lazy initialization #golang #lazyinit
