What is the difference between Promises and Observables in Angular 18?

Angular's asynchronous programming landscape is complex, with Promises and Observables playing crucial roles in modern web development. Understanding their differences and use cases is essential for creating efficient, responsive applications.

Key Differences Explored

In this comprehensive tutorial, we'll break down the fundamental distinctions between Promises and Observables in Angular 18:

• Single vs. Multiple Value Handling
• Error Management Strategies
• Cancellation and Resource Management
• Performance Considerations

Promises: One-Time Asynchronous Operations

Promises are ideal for single, one-time asynchronous operations. They resolve or reject once, making them perfect for scenarios like API calls where you expect a single response.

Observables: Powerful Data Streaming

Observables shine when dealing with continuous data streams, real-time updates, and complex asynchronous workflows. They offer powerful operators for transformation, filtering, and error handling.
