This example demonstrates a JavaScript data-processing report that loads car listings from an embedded JSON string, filters them by a price threshold, and formats each match into a readable line. It shows how to structure code into modular files using ES module exports, including `formatCar` for string interpolation and `generateReport` for chaining array methods like `filter` and `map`. The `getCars` function returns a Promise that simulates a 2‑second asynchronous delay before resolving the data. The rendered output appears as plain text in an HTML `<pre>` element, updated via the DOM’s `textContent` property.

Fork of Cars Report

This example demonstrates a simple data-reporting workflow that fetches a hard-coded JSON array of car listings and filters them by price. It shows how modular JavaScript functions, including `formatCar` and `generateReport`, process the data to display a text report of vehicles under $2,000 in a large `<pre>` element. The code uses the native `Promise` API with a simulated two-second delay in `getCars`, and relies on `JSON.parse` for data parsing. The page initially shows “Loading...” before the report appears, illustrating asynchronous data handling with plain ES modules.

Fork of Cars Report

This example demonstrates how to build a data report by filtering and formatting car listings. It retrieves a hardcoded JavaScript object array via a simulated asynchronous function, filters entries where the price is below a specified threshold, and formats each result into a readable string line. The final output is displayed as plain text in an HTML `<pre>` element. The code relies on JavaScript ES6 module syntax, `Promise`-based loading, `JSON.parse`, array filtering, mapping, and string joining.

Fork of Cars Report

This example demonstrates a JavaScript data-processing pipeline that loads car data, filters by price, and formats the results into a text report displayed on a web page. It uses the native `fetch`-like pattern through a custom `getCars` function that returns a Promise wrapping a hardcoded JSON array, simulating asynchronous data retrieval. The code exercises ES6 modules with `import`/`export`, array methods like `filter` and `map`, and template literals in the `formatCar` utility. The final output appears in a `<pre>` element after a two-second simulated delay.

Fork of Cars Report

This example demonstrates a JavaScript data-processing pipeline that reads a car inventory from an embedded JSON array, filters the cars by price, and formats the results into a text report. The interface shows a clear output panel, initially displaying a loading message. The code uses a custom `getCars` function, which simulates an asynchronous API call with a two-second delay, and a `generateReport` module that filters and maps car objects. The final formatted list is rendered into the HTML page using the `textContent` property of a designated `<pre>` element.

Fork of Cars Report

This fork demonstrates a simple JavaScript report generator using ES6 modules and asynchronous data loading. It parses an embedded JSON array of five cars, filters them by a price threshold, and formats each result as a string with year, make, model, and price. The `getCars()` function returns a Promise that resolves after a two-second delay, simulating an API call. The final report replaces a “Loading...” message in the page’s `<pre>` element, showcasing object destructuring and array methods like `filter` and `map`. The example also includes a separate test file that accesses car data directly.

Fork of Cars Report

This example demonstrates a JavaScript workflow that fetches car data and dynamically generates a formatted text report. It shows how modular code separates data retrieval, formatting, and report generation. The page initially displays “Loading...” and then presents a list of cars priced under $2,000, using a Promise with `setTimeout` to simulate an asynchronous API call. The implementation relies on ES6 modules, `JSON.parse` for handling embedded data, array methods like `filter` and `map`, and template literals for string construction. The visual output is plain text rendered directly into an HTML `<pre>` element.

Fork of Cars Report

This example demonstrates how to generate a text-based car report by filtering a built-in JavaScript array of car objects based on a maximum price threshold. It uses asynchronous data loading via a custom `getCars()` function that returns a Promise, simulating a delay before rendering the filtered list. The report is composed through modular functions, `formatCar` and `generateReport`, which utilize array methods like `filter` and `map` to produce formatted strings. The final output is displayed in an HTML `<pre>` element, updated after the Promise resolves.

Fork of Cars Report

This example demonstrates a JavaScript data-processing pipeline that fetches car listings, filters them by price, and formats them into a text report. It shows how asynchronous data loading, array methods, and module imports work together to build a dynamic message displayed on the page. The code uses `getCars()`, a promise-based function that simulates a two-second API delay, and `generateReport()` which calls `filter()` and `map()` before joining results. The report is rendered as plain text in an HTML `<pre>` element, with styling set via inline CSS.
