What are the differences between lazy loading and eager loading in JavaScript frameworks?

What are the differences between lazy loading and eager loading in JavaScript frameworks?

Lazy loading loads resources only when they are needed, while eager loading loads all resources upfront.

Can you give me examples of when to use each method?

Use lazy loading for images on a long page to improve initial load time, and eager loading for critical scripts needed immediately.

What are the performance implications of each approach?

Lazy loading can enhance performance by reducing initial load time, but may introduce delays when resources are requested later.

Are there any frameworks that support these loading strategies?

Yes, frameworks like React and Vue support lazy loading through dynamic imports, while others may have built-in eager loading options.
