This example shows a simple car report generator that fetches a hardcoded JSON dataset of five vehicles, filters them by price under $2,000, and displays the results as formatted text lines. The page initially shows “Loading...” while the code uses a Promise-based `setTimeout` delay in `getCars()` to simulate an asynchronous data fetch. JavaScript modules (`import`/`export`) organize the logic, with `formatCar` handling string interpolation for year, make, model, and price, and `generateReport` chaining `filter()`, `map()`, and `join()` to build the final output into a `<pre>` element.

Cars Report

This example demonstrates how to generate a plain-text car report by filtering a hardcoded JSON array of five vehicles and formatting each result. The page initially shows “Loading…” and then displays a list of cars priced under $2,000 after a simulated two-second delay. The code uses JavaScript modules with `export`/`import` to separate data retrieval (`getCars` returning a Promise), formatting via `formatCar`, and filtering/joining logic in `generateReport`. The final output is rendered into a `<pre>` element using `textContent`.

Cars Report

This example demonstrates a simple car report generator that filters a hardcoded JSON dataset of five vehicles by maximum price and displays the results as formatted text. The app begins with a loading message, then uses the `getCars()` function to simulate a two-second asynchronous fetch via a `Promise` and `setTimeout`. Once resolved, the `generateReport()` function chains `filter()` and `map()` to select cars under $2,000, formats each entry using `formatCar()` to produce strings like “2009 Ford F150: $1950”, and joins them with line breaks into the `message-element` of the page. The code uses standard JavaScript APIs (ES6 modules, `Promise`, `JSON.parse`) without additional visualization libraries.

Cars Report

This example demonstrates a text-based car report generated from a JSON array of five used vehicles, filtering by price and formatting each entry as a readable line. It illustrates asynchronous data handling with a `Promise` and `setTimeout` in `getCars.js`, while `generateReport.js` chains `filter`, `map`, and `join` to produce the final output. The page uses a `<pre>` element in `index.html` to display the result, with JavaScript modules (`import`/`export`) orchestrating the logic. The report updates after a simulated two-second delay, showing only cars priced under $2,000.

Cars Report

This example demonstrates how to generate a text-based car report, filtering a hardcoded JSON dataset of five vehicles by price and formatting each entry as a single line with year, make, model, and cost. It shows an asynchronous loading state before displaying the final report in a large `<pre>` element. The code uses ES6 modules, `JSON.parse`, a `Promise` with `setTimeout` to simulate a data fetch, and `Array.filter` combined with `Array.map` and `join` via exported functions `getCars`, `formatCar`, and `generateReport`.

Cars Report

This example demonstrates generating a text-based report of cars, filtering a hardcoded JSON dataset to display only vehicles priced under $2,000. The interface shows a loading message before asynchronously fetching the data. It uses JavaScript objects, arrays, and modules, with asynchronous operations powered by a Promise and `setTimeout` to simulate a network request. The report is formatted through custom functions, `formatCar` and `generateReport`, using array methods like `filter`, `map`, and `join`. The result is displayed in an HTML `<pre>` element, styled for readability.

Cars Report

This example demonstrates a text-based report generated from car data, filtering vehicles under a price threshold and formatting each entry with year, make, model, and price. It uses a JavaScript promise—`getCars()`—to simulate asynchronous loading with a two-second delay, then displays a loading message before rendering the final report in the browser via `textContent`. The modular approach imports `formatCar` and `generateReport` to handle data transformation, relying on `JSON.parse` for the inline car dataset.

Cars Report

This example shows a text-based report of cars, listing each vehicle’s year, make, model, and price if it falls under a set maximum price. The page initially displays “Loading...” before fetching data asynchronously via a Promise from `getCars`, which simulates a two-second delay with `setTimeout`. Once loaded, the `generateReport` function filters the parsed JSON array and formats each entry using `formatCar`, then writes the multiline result to a `<pre>` element in the DOM. The code relies on native JavaScript methods like `Array.filter`, `Array.map`, and `Array.join`, with no external visualization libraries.

This example demonstrates generating a text-based car report by filtering a list of used vehicles under a price threshold and formatting each entry with year, make, model, and cost. It loads data as a JSON array via the `getCars` function, which returns a Promise that simulates async fetching with `setTimeout`. The report is built using `Array.filter`, `map`, and `join` in `generateReport`, with `formatCar` handling string interpolation. The final output appears in a `<pre>` element after a brief “Loading…” state, showcasing modular JavaScript with ES6 exports and imports.
