This example demonstrates how to sort an array of objects by a key using D3’s `ascending` comparator within a JavaScript `sort()` method. The code defines three entries with keys and values, then logs the sorted array to the console. It relies on the D3 library version 7.8.5, importing the `ascending` function from the `d3` module. The example highlights a concise alternative to manual comparator logic, with commented-out code showing a `reduce` operation for future object transformation.
