Introduction

Signals are the new standard for reactivity in Angular. They provide a granular way to track state changes and update the UI efficiently.

Why Signals?

Unlike RxJS BehaviorSubject, Signals are:

• Synchronous
• Glitch-free
• Integrated deeply into the framework

import { signal, computed } from '@angular/core';

const count = signal(0);
const double = computed(() => count() * 2);

count.set(5);
console.log(double()); // 10
