Note: This page demonstrates basic code syntax highlighting using Astro's built-in features.

Code Block Demo

This page demonstrates how to use code blocks in your Markdown content.

Basic Usage - Code Blocks

Regular code blocks work with triple backticks:

// Regular markdown code block
function helloWorld() {
  console.log("Hello, world!");
}

JavaScript Example

// JavaScript example
function helloWorld() {
  console.log("Hello, world!");
  return true;
}

const result = helloWorld();

CSS Example

/* CSS example */
.container {
  display: flex;
  flex-direction: column;
  align-items: center;
}

.button {
  padding: 0.5rem 1rem;
  background-color: #6272a4;
  color: white;
  border-radius: 4px;
}

TypeScript Example

// TypeScript interface and implementation
interface User {
  id: number;
  name: string;
  email: string;
  isActive: boolean;
}

class UserService {
  private users: User[] = [];
  
  constructor() {
    console.log("User service initialized");
  }
  
  addUser(user: User): void {
    this.users.push(user);
  }
  
  getUserById(id: number): User | undefined {
    return this.users.find(user => user.id === id);
  }
  
  getAllActiveUsers(): User[] {
    return this.users.filter(user => user.isActive);
  }
}

// Usage
const service = new UserService();
service.addUser({
  id: 1,
  name: "John Doe",
  email: "john@example.com",
  isActive: true
});
