Intermediate Usage Tutorials

Welcome to the intermediate usage section of the MSDN documentation. This section dives deeper into practical applications and common scenarios, building upon the foundational knowledge acquired in the beginner tutorials.

1. Working with Asynchronous Operations

Understand the importance of asynchronous programming for responsive applications. Learn about Promises, async/await, and how to manage concurrent operations effectively.

Key Concepts:

• Understanding the Event Loop
• Callbacks and Callback Hell
• Introduction to Promises
• Using async and await
• Error Handling in Asynchronous Code

2. Data Management and Persistence

Explore various methods for managing and storing data, from local storage to more robust database integrations. Learn about caching strategies and data synchronization.

Topics Covered:

• Browser Local Storage vs. Session Storage
• Introduction to IndexedDB
• Working with Web SQL (deprecated but useful context)
• Caching Strategies for Performance
• Data Binding and State Management

// Example of using Local Storage
const userData = {
    name: "Alice",
    id: 123
};
localStorage.setItem('userPreferences', JSON.stringify(userData));

const storedData = JSON.parse(localStorage.getItem('userPreferences'));
console.log(storedData.name); // Output: Alice
            

3. Interacting with APIs

Learn how to fetch data from external services and communicate with backend APIs using standard web technologies like Fetch API and XMLHttpRequest.

Details:

• Making HTTP Requests (GET, POST, PUT, DELETE)
• Handling JSON Data
• Authentication and Authorization Headers
• Understanding RESTful Principles
• Error Handling for API Calls

4. Advanced UI Patterns

Discover sophisticated UI patterns that enhance user experience, including lazy loading, infinite scrolling, and component-based design principles.

Patterns:

• Implementing Lazy Loading for Images and Components
• Creating Infinite Scroll Lists
• Responsive Design Techniques
• Introduction to Web Components

5. Performance Optimization

Optimize your applications for speed and efficiency. Learn techniques for reducing load times, improving rendering performance, and minimizing memory usage.

Optimization Techniques:

• Code Splitting and Bundling
• Image Optimization
• Minification and Compression
• Browser Caching
• Performance Profiling Tools
