Memoization is a technique used to optimize the performance of a function by caching its results for a given set of inputs.

The idea is that if a function is called multiple times with the same input, it's more efficient to return the cached result instead of re-computing the result each time.

Data virtualization using Proxies in JavaScript refers to the ability to create virtualized data structures, such as virtualized arrays, that load their data on demand rather than loading all data at once.

This can be useful for improving the performance of an application when working with large data sets.
In this Eg., we create a VirtualArray class that takes in two args- the length of the array & a loader function.

A WeakMap is a map that holds weak references to its keys.
This means that the keys are eligible for garbage collection if there are no other references to them.
This feature can be useful for implementing caches or other similar data structures.

A WeakMap is a special kind of map where keys must be objects and the map doesn't prevent garbage collection of its keys.
You can think of a WeakMap as a map that doesn't "own" its keys, and therefore doesn't keep them alive.
