This example demonstrates a JavaScript data-processing pipeline that fetches a JSON array of car listings and outputs a formatted text report of cars priced under $2,000. The `getCars` function simulates a delayed API response using a Promise and `setTimeout`, while `generateReport` filters and maps the data with `filter` and `map`, producing a newline-separated summary via `join`. The final report is rendered directly into an HTML `<pre>` element using `textContent`, with a "Loading..." placeholder shown initially.

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.

Fork of Cars Report

This example demonstrates a JavaScript module pipeline that fetches car data and displays a filtered text report. It shows a list of vehicles priced under $2,000, formatted with year, make, model, and price. The code uses `getCars()` with a `Promise` and simulated delay to return `JSON.parse` data, then applies `generateReport()` with `filter()` and `map()` to format entries via `formatCar`. Results appear in an HTML `<pre>` element, with `Loading...` shown initially until the asynchronous data arrives.

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 a simple asynchronous data-reporting workflow, loading a static JSON array of five used cars and generating a filtered list of those priced under $2,000. The code uses `Promise`-based `getCars()` with a simulated 2-second delay, then renders the final text into an HTML `<pre>` element via `document.getElementById`. It highlights modular JavaScript with ES modules, including `export`/`import` syntax and array methods like `filter` and `map`, showing how to structure reusable functions (`formatCar`, `generateReport`) for text-based output.

Fork of Cars Report

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 text-based report that filters a list of cars by price and displays formatted entries. The page initially shows “Loading...” and, after a two-second simulated delay, renders a report of cars under $2,000. The code uses JavaScript modules and Promises, with `getCars` returning a hardcoded JSON array of car objects, and `generateReport` filtering and formatting each item via `formatCar`. The final output is written into a `<pre>` element.

Fork of Cars Report

This example demonstrates a simple report generator that filters and formats car listings by price. It uses JavaScript modules, arrays, objects, and Promises to load data and produce a text-based message. The code relies on `getCars()` to return a hardcoded JSON dataset after a simulated delay, then `generateReport()` filters cars under $2,500 and formats each entry with `formatCar`, which outputs year, make, model, and price. The final report appears inside an HTML `<pre>` element.

Fork of Cars Report

This example demonstrates how JavaScript objects, arrays, and modules can build a simple text-based car report. It filters a hardcoded JSON dataset of five cars by price, formats each qualifying entry with the `formatCar` function, and displays the results in a large HTML `<pre>` element. The code uses `Promise` and `setTimeout` in `getCars.js` to simulate an asynchronous data fetch, while `generateReport.js` chains array methods like `filter`, `map`, and `join`. The visualization is purely textual, updating the page from "Loading..." to the final list after a two-second delay.
