This example demonstrates how JavaScript arrays can be generated with random numeric values, using a series of helper functions defined in vanilla JavaScript. It shows the output of a `randomrandom` function that creates an array of arrays, where each inner array contains random integers or decimals between a minimum and maximum range. The code defines `range`, `random`, and `randomrandom` functions—`randomrandom` recursively calls `random` to build nested arrays, with an option for rounding values. The result is logged to the browser console via `console.log`, with no visual rendering or external libraries involved.
