Angular 21 Tutorial in Hindi #29 | Signals Deep Dive | Fine Grained Reactivity & Signal Graph

In this video, we take a deep dive into Angular 21 Signals and understand how Angular achieves fine-grained reactivity.

You’ll learn how the Signal Graph works behind the scenes, how Angular updates only the required parts of the UI, and how Signals help avoid over-rendering, leading to major performance improvements.

This video is ideal for intermediate to advanced Angular developers who want to master performance and internal reactivity concepts.

📘 What You’ll Learn
-- What is fine-grained reactivity in Angular
-- How Signals track dependencies
-- Understanding the Signal Graph
-- Why Signals prevent unnecessary re-renders
-- Performance benefits over traditional change detection
-- Best practices for using Signals
-- Angular Signals interview questions
