Thinking about switching from Java to Go?
The biggest wins aren’t fancy frameworks — it’s the everyday differences that change how you design and debug.
Here are 6 I’ve found most valuable:
•
Explicit error handling (not hidden exceptions)
•
Interfaces declared at usage, implemented implicitly
•
Constructors to prevent nil‑crashes
•
Receiver vs nil semantics (know when calls are safe)
•
Bytes vs runes vs user text (strings ≠ chars)
•
GoFmt is a baseline, naming still matters
Full breakdown (with Java
Go side‑by‑side examples):
