What are the differences between JavaScript engines?

What are the main differences between JavaScript engines like V8 and SpiderMonkey?

V8 is developed by Google and is known for its performance and optimization, while SpiderMonkey is Mozilla's engine, focusing on standards compliance and features.

Which engine is better for web development?

It depends on your needs. V8 is often preferred for performance-intensive applications, while SpiderMonkey is great for compatibility with web standards.

How do these engines handle memory management?

Both engines use garbage collection, but their algorithms differ. V8 uses a generational garbage collector, while SpiderMonkey has a more traditional approach.

Can I use both engines in the same project?

Generally, you would choose one engine per project, as they are designed to work with specific environments (like Node.js for V8 or Firefox for SpiderMonkey).
