This example demonstrates a JavaScript array-shuffling algorithm. It creates an array containing the numbers 1 through 90, then randomizes the order of those elements using the Fisher–Yates shuffle technique. The shuffled array is output to the browser’s console via `console.log`. The page uses no external libraries; it relies solely on vanilla JavaScript and the native `Math.random` function for randomness. The code is embedded directly in a minimal HTML file and executes on page load, with commented-out variations showing alternate array sizes.
