Angular Templates: Interpolation
🎯 What is Interpolation in Angular?
Interpolation is a technique in Angular templates that allows you to display data from your component class into the HTML view.
It uses the double curly braces:
Interpolation = Component data → Template display

🧠 What Can You Do with Interpolation?
1️⃣ Display Variables
2️⃣ Perform Simple Calculations
3️⃣ Use Methods
4️⃣ Access Object Properties
5️⃣ Convert or Format Data
⚠️ What Interpolation Cannot Do
❌ You cannot assign values:
❌ You cannot use if-else or loops directly:
(Use *ngIf and *ngFor instead)
❌ No new objects or heavy logic.
Interpolation should remain simple and fast.
💡 How Angular Processes Interpolation
-
Looks at
{{ ... }} -
Reads data from Component class
-
Updates the DOM automatically
-
If data changes → UI updates instantly
(This is Angular’s data-binding system)
✔️ Real-Life Example
TS
🎉 Summary: Interpolation in One Line
👉 Interpolation binds component data into HTML using {{ }} and shows dynamic content on the page.
