State management is the beating heart of any front-end application. The way we handle it determines not just performance, but also developer experience and scalability.
๐ The State Management Landscape
For years, _React _and _Angular _have taken very different paths to state management:
React: Started with setState, evolved to Hooks (useState, useReducer, useContext), and now sees many developers adopting libraries like Redux, flux, or even React Signals (via third-party packages).
Angular: Relied heavily on RxJS and services for reactive state โ until Signals arrived in Angular 16+ as a built-in, framework-native reactivity model.
โ๏ธ React's Approach
Pros:
- Extremely flexible โ choose the library that fits your needs.
- Mature ecosystem with huge community support.
Cons:
- No single โofficialโ way to manage state.
- Prone to unnecessary re-renders if not optimized.
- Steeper learning curve when combining multiple tools.
`import { useState } from "react";
function Counter() {
const [count, setCount] = useState(0);
return (
setCount(c => c + 1)}>
Count: {count}
);
}`
๐ ฐ Angular Signals
Signals in Angular are reactive primitives that store a value and notify dependents when it changes โ without the boilerplate of RxJS for simple cases.
Pros:
- Framework-native: No extra dependencies.
- Fine-grained reactivity: Updates only where needed.
- Simplifies complex reactive flows without RxJS overhead.
Cons:
- Still new โ ecosystem catching up.
- Requires Angular 16+.
`import { signal } from '@angular/core';
export class CounterComponent {
count = signal(0);
increment() {
this.count.update(c => c + 1);
}
}
`
โก Performance
React: Relies on Virtual DOM diffing; optimizations require memo, useMemo, useCallback.
**
Angular Signals:** Tracks dependencies explicitly, skipping full component re-renders when not needed.

๐ Final
While React remains incredibly versatile, Angular Signals represent a leap forward in state management efficiency. Their native integration, fine-grained updates, and simplified API make them a strong contender โ and in my view, the better long-term bet for apps built in Angular.
๐ก Best Practices
- In React: Use memo and useCallback aggressively.
- In Angular: Use Signals for local state, RxJS for streams.
