There're 2 states of every programmer:

1) I'm a God.

2) I have no idea what I'm doing.

If you want to learn how to do better code reviews,
here are some tips for sharing feedback:


Wording makes a huge difference.

If you apply these techniques, your teammates will appreciate you.

---

❌ This is wrong
✅ This approach might cause issues with concurrent access. Why do you think about using a lock here - similar pattern in our auth service?

↳ specifc problem + solution + context

---

❌ Why didn't you just...
✅ I wonder if we could simplify this with Array.reduce()? It might be more readable for large datasets.

↳ collaborative tone + explain benefits

---

❌ This doesn't follow our standards.
✅ This doesn't match our error handling pattern. Check out our style guide section 4.2 (include link). We use the Result Pattern for such cases.

↳ specific reference + actionable guidance

---

❌ This should use the new pattern we adopted last month.
✅ This could use the new pattern we adopted last month. What do you think?

↳ doesn't give command + allow the other person to let their guard down

---

❌ nit: fix formatting
✅ Set up Prettier/ESLint and focus reviews on logic, architecture, and edge cases.

↳ automate the trivial, focus on what matters

---

Remember:
↳ Code reviews should build people up, not tear them down.
↳ Review the code, not the person!

Ultimately, the goal is to ship reliable code, not win arguments.

If a function accepts multiple parameters of the same type, 

⚠️ We may accidentally pass arguments in the wrong order. 

Types can't protect us.

Instead...

✅ Accept an object.

3 simple guidelines for better naming:

1. Classes: use nouns

❌ class MapPaymentMethod
✅ class PaymentMethodMapper

2. Functions: use verbs

❌ emailSend()
✅ sendEmail() 

3. Booleans: use adjectives

❌ active
✅ isActive

Small change → Big impact.

Is optimizing every line of code worth your time?

Over the years, I’ve worked on several React projects.

Along the way, I’ve learned some valuable lessons about performance optimization.

Not all performance issues are equal.

It’s important to focus on the ones that make the biggest difference.

I wrote an article about seven practical tips on performance optimizations in React applications.
