💡 Essential Rules for a Smooth Update

1. Check Node Version Compatibility 🚦🔍🔧
   Angular updates often require specific Node versions. Make sure you're aligned before starting.

2. Use the Correct Node Version During Updates 🛠️🔑🔄
   Run installs with the matching Node version. Upgrade Angular using a higher version afterward.

3. Don't Force Updates ⚠️🙅‍♂️🚫
   Avoid using --force. It's better to fix the underlying issues before pushing forward.

4. Clean Up Unused Packages 🧹🗑️🎯
   Encountering stubborn packages? Check if they're even being used. If not, remove them. Less baggage means fewer problems.

5. Run Tests Frequently – My Personal Mistake 🧪✅⚙️
   I once tested everything very superficially and ended up with tons of bugs – big and small. Lesson learned: test thoroughly and often, especially after updates.

Additionally: While testing after each update might take more time and require fixing more bugs along the way, it's absolutely worth it. In the long run, this strategy will save you more time and nerves by preventing the accumulation of hard-to-debug issues later. 🕒🛠️😌
