How this Angular track works
- Real Angular 19 in the playground — Angular core, platform-browser, and common load from CDN; your TypeScript compiles in the browser when you click Run in browser.
- Original lesson copy — we explain patterns and trade-offs in our own words; use official docs as reference, not a script to paste.
- Prerequisites — finish JavaScript (functions, objects, arrays, async) and TypeScript (types, classes, decorators). Angular builds on both.
Use printOutput(...) for terminal values and mountApp(Component) when a lesson shows a live UI preview in the iframe.
Install on your device (macOS, Linux, Windows)
Lessons run in your browser on this site—install a modern browser and optional editor for local projects.
macOS
- Use Safari (preinstalled) or install Google Chrome / Firefox.
- Optional editor: VS Code (
brew install --cask visual-studio-code). - Open DevTools with ⌥⌘I (Chrome/Edge) or ⌥⌘C (Safari Web Inspector).
Linux
- Install Chromium or Firefox:
sudo apt update && sudo apt install -y chromium-browser firefox(Debian/Ubuntu; package names vary by distro). - Fedora:
sudo dnf install -y chromium firefox. - Optional editor: VS Code from code.visualstudio.com or
sudo snap install code --classic.
Windows
- Install Microsoft Edge or Chrome.
- Optional editor: VS Code (
winget install Microsoft.VisualStudioCode). - Open DevTools with F12 or Ctrl+Shift+I.
Verify: Open any lesson playground and click Run—output appears without installing a compiler.
Local CLI: npm install -g @angular/cli then ng new my-app.
Angular is a TypeScript platform for building enterprise web applications with components, dependency injection, routing, and a CLI-driven workflow.
How this track differs from plain JavaScript
If you completed the JavaScript track, you already know functions, objects, and async. Angular organizes UI into components with TypeScript, decorators, and dependency injection.
Our TypeScript track teaches static types—Angular assumes them in real projects. Compare lightly with React and Vue when choosing a framework.
What you will learn
- Standalone components, templates, and built-in directives
- Signals, computed values, and effects
- Dependency injection and services
- Forms, routing concepts, HttpClient, and production habits
Playground setup
Angular 19 loads from CDN. Early lessons use printOutput(...); from standalone components onward use the global Ng namespace, @Component, selector app-root, and mountApp(Component).
