This example demonstrates JavaScript boolean operators by evaluating and displaying the results of `(a && b)` and `(a || b)` directly in the browser. It uses the `document.write()` method to output the operand values and their combined results, with each result separated by an HTML line break. The page relies on plain JavaScript embedded in an HTML body, with no external libraries or frameworks, showcasing a minimal approach to testing logical expressions in a static web page.
