This example displays the output of four JavaScript exercises from Chapter 5 of Eloquent JavaScript, all run in the browser console. It shows array flattening using `reduce`, a custom `loop` function, an `every` predicate implementation with `filter`, and a `dominantDirection` function that uses `countBy` and `characterScript` to classify text direction. The code relies on the standard JavaScript array methods and the predefined `SCRIPTS` dataset. The page renders only static text and styled body text via CSS, with results logged to the console.
