From Java to Go: My Journey with Golang 🚀

I worked with Java for many years, building backend systems, APIs, and distributed applications.

In 2022, I decided to focus more on Golang. I had studied it a little before, but I wanted to use it in real projects and really understand it.

Why I Like Programming in Go?

• Go is simple, fast, and fun to write. Here are some things I noticed while moving from Java:
• Simple syntax: Less boilerplate than Java. Easy to read and understand.
• Fast performance: Compiles to native code and runs quickly, especially for CPU-heavy tasks.
• Concurrency made easy: Goroutines and channels make running multiple tasks simple.
• Explicit error handling: No exceptions like Java. You check errors directly, which makes programs safer.
• Easy deployment: Produces a single executable, no JVM or extra setup needed.
• Fun to code: Every day I discover new things, which makes me enjoy coding even more.

My Go Experience 🛠️

Since 2022, I have applied Go in real projects:

• Built REST APIs and microservices.
• Worked with event-driven architectures.
• Managed high-volume data in production systems.
• Followed best practices in code design, testing, and monitoring.

I keep learning new tips and tricks every day. Even small features or idioms make my code cleaner and faster.

Comparing Go and Java ⚖️

• Go is lighter and faster for many backend tasks.
• Java can be verbose but is still strong for large enterprise systems.
• Concurrency in Go feels more natural than Java threads.
• Go’s error handling encourages safer code.
• Deployment in Go is simpler, especially for microservices and cloud apps.

Final Thoughts ✨

If you come from Java or another language, I highly recommend trying Go. It is simple, fast, and enjoyable. And even after months of using it, I keep learning something new every day, which makes the language exciting and motivating.
