Implementing a Batcher Function to Ensure a Single Execution of a Synchronous Array‑Doubling Function

This article explains how to wrap a synchronous function that doubles array elements so that multiple calls return the expected doubled results while the underlying function is executed only once, using clever tricks, setTimeout‑based debouncing, and Promise‑based micro‑task scheduling.
