Exercise: The Lazy Buffer
Practice how to create a factory function that generates a virtual proxy for a buffer.
We'll cover the following...
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 ...
