Mastering Angular’s Change Detection with OnPush and markForCheck() 🚀

🛠️ Want to supercharge your Angular app’s performance?
Switch to OnPush Change Detection! Angular’s default strategy checks every component, even when nothing changes, which can slow down large apps.

✅ Here’s why you should use OnPush:

Angular only checks components when their inputs change or an event triggers.

It’s a huge performance boost when working with large apps and dynamic data.

🔧 Quick Fix: Use markForCheck() when you need to manually trigger change detection. This ensures that even components with OnPush are checked when needed!

💬 How has OnPush changed the way you build Angular apps? Let me know how ChangeDetection strategies are affecting your apps!

How markForCheck() Enhances Angular Performance 🔧

💡 Let’s talk about markForCheck() in Angular!
When you’re using OnPush change detection, you need a way to manually trigger a check for changes in the component’s view.

🚨 Enter markForCheck()!
This method explicitly tells Angular to check the component view, even when it’s using the OnPush strategy.

📍 When should you use markForCheck()?

When you need to manually trigger a check after an asynchronous operation (like an API call).

When you’re dealing with dynamic content that Angular might not notice without explicit marking.

💬 Have you used markForCheck() in your projects?
Let’s discuss some real-world examples of how you’ve used this in your Angular applications!
