Summary

This video tutorial explains how to use model signals in Angular 19, offering a more efficient approach to two-way data binding compared to traditional `ngModel` with instance variables. It demonstrates using signals with both string and object types, highlighting the benefits of using the `update` and `set` methods for signal manipulation and utilising the `effect` method for tracking signal changes.

Highlights

➡️ Model Signals in Angular 19: The tutorial introduces the use of model signals as a superior alternative to traditional `ngModel` for two-way data binding in Angular 19.
💡 Improved Performance: Signals offer performance advantages over previous methods, reducing the need for change detection and zone.js overhead.
🔄 `set` and `update` Methods: The video details the use of the `set` method (for direct value assignment) and the `update` method (for value updates based on the current value) within signals.
➕ Tracking Changes with `effect`: The `effect` method is showcased as a way to easily track changes in signal values and perform actions based on these changes.
📦 Object Support: The tutorial demonstrates the use of model signals with object types, showing how to bind and update nested properties within the signal.
