Angular 21 Just Changed Templates Forever (Spread Syntax)
Angular 21 is here, and it finally killed the need for template-formatting getters in your TypeScript.
In this video, I break down the new Spread Syntax in Angular 21 templates. We used to waste memory creating new object references just to format data for the UI. Now, the Angular 21 compiler optimizes this as a "pure function."
What we cover:
The Deprecated Pattern: Why get mergedData() is now bad practice.
The Architecture: How Angular 21's change detection ignores these object literals unless data actually changes.
The Code: Using ...spread inside @let blocks.
