🚨 Go feels simple β€” until it bites you.

In 2025, many Go teams still ship code with silent leaks, random panics, and ghost goroutines. Why? Anti-patterns.

⚑ Top mistakes to dodge:

  • Fire-and-forget goroutines without context β†’ πŸ’₯ leaks & memory chaos
  • Swallowed errors β†’ πŸ’£ bugs hiding in plain sight
  • Closing channels from the wrong place β†’ πŸŒ€ random panics
  • WaitGroup imbalance β†’ 🧨 mysterious deadlocks
  • Panic on bad input β†’ 😱 whole service down from one bad request
  • Interface{} everywhere β†’ 🀷 compiler can’t help you anymore
  • Hidden globals β†’ πŸ”₯ data races no one can see
  • Slice aliasing traps β†’ πŸͺ€ unexpected side effects
  • defer inside loops β†’ 🐘 file descriptor explosion

βœ… Learn when to use context, how to own channels, avoid slice traps, and more.
