Exercise: The Lazy Buffer

Explore how to implement a createLazyBuffer function in Node.js that delays buffer allocation until the write method is invoked. Understand the Proxy pattern's role in managing resource allocation efficiently. This lesson helps you grasp creating virtual proxies to optimize memory use in buffer handling within structural design patterns.

Problem statement

Can you implement a createLazyBuffer(size) named factory function that generates a virtual proxy for a buffer (Buffer) of the given size? The proxy instance should instantiate a Buffer object (effectively allocating the given amount of memory) only when write() is being invoked for the first time. If no attempt to write into the buffer is made, no ...
