Angular In a Nutshell

The History of Angular: A Love Story (Sort Of)

Once upon a time, in 2009, Misko Hevery and the brilliant minds at Google decided that building dynamic web applications with plain JavaScript was a nightmare.

So, they invented AngularJS, a framework that promised developers a better life filled with two-way data binding and directives.

But like all love stories, things got complicated. AngularJS was great but had performance issues and wasn’t built for modern apps.

So in 2016, Google dropped a bombshell: Angular 2, a complete rewrite using TypeScript, and they told everyone to move on. 😱

Fast forward to today, Angular (no “JS” in the name anymore) is a powerful framework for building scalable, maintainable, and enterprise-level applications.

It’s component-based, reactive, and highly opinionated—meaning you play by its rules, or it gets mad.

Angular vs. AngularJS: What’s the Difference?

What Makes Angular Special?

Angular is opinionated and comes with everything built-in:

• TypeScript First – Because JavaScript can be a hot mess.
• Component-Based Architecture – Reusable and modular.
• Dependency Injection – Manage dependencies like a boss.
• Two-Way Data Binding – Keep your data and UI in sync.
• RxJS for State Management – Reactive programming made easy.
• Built-in Routing – No need for third-party libraries.

import { Component } from '@angular/core';

@Component({
  selector: 'app-hello',
  template: `<h1>Hello, Angular!</h1>`,
  styles: ['h1 { color: red; }']
})
export class HelloComponent {}

import { NgModule } from '@angular/core';

import { HomeComponent } from './home.component';

const routes: Routes = [
  { path: 'home', component: HomeComponent }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule {}

3. Service & Dependency Injection

How Does Angular Compare to React?

Wrapping Up

Angular is powerful, structured, and enterprise-ready, but it does come with a learning curve. If you need a full-fledged framework with everything built-in, Angular is a great choice. If you prefer flexibility and a lighter approach, React might be your thing.

Either way, whether you’re in Team Angular or Team React, you’re doing modern web development, so you’re winning! 🎉

Key Takeaways

• Angular was created by Google and has evolved significantly from AngularJS.
• Angular is a full framework with built-in tools for routing, state management, and dependency injection.
• React is a UI library, meaning you need extra tools for things like routing and state management.
• Angular is great for large-scale applications, while React is lightweight and flexible.
• Both are component-based, making modern web development modular and scalable.
