This example demonstrates how JavaScript can fetch and report used car listings by applying filtering and formatting logic. It shows a car report generated as text, displaying only vehicles priced under $2,000, with each entry formatted as “year make model: $price.” The visualization relies on asynchronous data loading via `getCars`, which returns a promise resolving after a simulated delay, and then uses `generateReport` to filter the parsed JSON array and map each car through the `formatCar` function. The result is rendered into a `<pre>` element on the page, updating its text content from “Loading…” to the final report.

This example demonstrates a simple text-based report of used cars, filtering a static JSON dataset to display only vehicles priced under $2,000. It shows how asynchronous JavaScript loads data with a simulated delay via `Promise` and `setTimeout`, then formats each car’s year, make, model, and price into a readable string. The code uses `getCars()` to fetch the inline JSON array, `generateReport()` with `filter` and `map` to process entries, and a custom `formatCar` function to build the output, which is inserted into an HTML `<pre>` element. The visualization relies on standard JavaScript object manipulation and module exports, with no external charting libraries.

Cars Report

This example demonstrates generating a text-based report of used cars priced under $2,000, displaying entries as formatted strings like “2000 Honda Accord: $2800” in a large HTML `<pre>` element. It uses JavaScript promises and a simulated 2-second delay via `getCars()` to load an inline JSON array of car objects. The `generateReport` function filters cars by price and maps each to a formatted line using the `formatCar` utility, with the final output rendered through the DOM. The visualization relies on core JavaScript array methods (`filter`, `map`, `join`) and modular imports, with no external libraries.

Cars Report

This example demonstrates a text-based report of used cars, filtering the data to show only vehicles priced under $2,000. The page initially displays a loading message before the report appears as formatted lines, each listing the year, make, model, and price. The code uses JavaScript promises with `getCars` to simulate a delayed data fetch and modules like `formatCar` and `generateReport` to transform a JSON array. The interface relies on DOM manipulation via `getElementById` and `textContent`.

Cars Report

This example demonstrates a text-based report of car listings, showing each vehicle’s year, make, model, and price, filtered to include only cars under a $2,000 threshold. It uses a simulated asynchronous data source via `getCars()` with a `Promise` and `setTimeout`, then processes the data with `generateReport()`, which applies `Array.filter`, `Array.map`, and `formatCar()` to build a formatted string. The output is displayed in a `<pre>` element, updated after a two-second loading delay using the DOM API `document.getElementById`. No external libraries are used, relying solely on vanilla JavaScript and HTML.

Cars Report

This example displays a car report by filtering a list of cars to include only those priced under $2,000, formatting each entry with the year, make, model, and price, and presenting the results as plain text. The page initially shows a “Loading...” message while `getCars` fetches the data from an embedded JSON array after a simulated two-second delay. The code uses JavaScript promises, array methods like `filter` and `map`, and template literals within the `formatCar` and `generateReport` functions, while the HTML and CSS style the output with a large white monospace font on a light blue background.

Cars Report

This example demonstrates a text-based report of car listings, filtering results to show only vehicles priced under $2,000 and formatting each entry as a year, make, model, and price line. The page initially displays a “Loading...” message, then uses a Promise from `getCars` to simulate a two-second delay before rendering the filtered data. The report is generated with `generateReport` and `formatCar` modules, which use JavaScript array methods (`filter`, `map`, `join`) on data parsed from an embedded JSON string.

Cars Report

This example demonstrates a simple text-based report of used cars filtered by price, displaying each vehicle’s year, make, model, and cost in a preformatted HTML element. It shows how JavaScript modules and Promises structure asynchronous data loading and transformation. The code uses `getCars()` to return a parsed JSON array after a two-second delay, then applies `generateReport` with `filter` and `map` to select cars under $2,000 and format them via `formatCar`. The final output is rendered into the DOM using `document.getElementById` and `textContent`.

Cars Report

This example demonstrates a simple text-based report of used cars, filtering a list to show only those priced under $2,000 and formatting each entry as a line with the year, make, model, and price. It relies on JavaScript modules and Promises, with `getCars` simulating an asynchronous API call via `setTimeout` and returning parsed JSON data. The `generateReport` function chains array methods like `filter` and `map`, while `formatCar` handles string interpolation for output. The final result is displayed in a `<pre>` element in the DOM.
