What is lazy loading and how is it implemented in different programming languages?

What is lazy loading and how does it work?

Lazy loading is a design pattern that postpones the initialization of an object until the point at which it is needed. This can improve performance by reducing the initial load time.

Can you give me examples of how lazy loading is implemented in JavaScript?

In JavaScript, lazy loading can be implemented using dynamic imports. For example, you can use import() to load a module only when it's needed.

What about in Python? How is lazy loading achieved there?

In Python, lazy loading can be achieved using generators or the lazy property in libraries like lazy-loader. This allows you to load data only when it's accessed.

Are there any performance benefits to using lazy loading?

Yes, lazy loading can significantly improve performance by reducing the amount of data loaded initially, leading to faster load times and better resource management.
