This example demonstrates how to display and format car data within an HTML page using plain JavaScript. It shows two separate text elements, each populated with car information from hardcoded JSON arrays, including filtering cars by year and formatting them into readable strings. The code uses the `document.getElementById` method to select elements, `JSON.parse` to convert JSON strings into JavaScript objects, and array methods like `filter`, `map`, and `join` to process and display the data. The second script appends its output to the first element's existing content.
