Memo-what?

Memoization is a technique for storing computed values in-memory. Essentially, it's a fancy name for in-memory cache.

Why Memoize?

Memoization is useful when you have potentially expensive or highly repetitive computations that need to be executed. Rather than re-running the computation on each iteration, your routine computes once and fetches already computed values from memory.

    if (err) {
