🧩 Still struggling with = vs ==? You’re not alone.

In 2025, rookie coding mistakes are rarely about logic — they’re about invisible rules.

⚠️ Common traps that still trip up new devs:

1. if (score = 10) ← assignment, not comparison
2. console.log("false") ← still truthy
3. Off-by-one loops
4. Floating-point decimals: 0.1 * 3 → 0.30000000000000004
5. Asynchronous surprises: fetch() returns later

✅ With clear examples and mental models — not just syntax rules.
