This example demonstrates a sequential asynchronous loop over an array, where each item is processed only after the previous callback completes. It shows how `asyncForEach` awaits a user-provided callback that delays execution using a custom `waitFor` promise wrapper around `setTimeout`. The code uses the native `async`/`await` syntax and a `for` loop to ensure the array `[1, 2, 3]` is logged in order, with a one-second pause between each item. The visible data source is a hardcoded array in the `start` function, and the rendering approach is console output.

Gist c0ec6bb768fd2672307b0807e4ee46fb

This example benchmarks four JavaScript loop styles—a standard `for` loop, a reversed `for` loop, a `for…of` loop, and `forEach`—on a fixed array of ten numbers. It measures execution time by repeating each loop a thousand times via `performance.now()` timestamps, accumulating the total milliseconds. The code defines each loop as a separate function and calls them through a `test` helper, logging the sum to the console. The comparison uses a simple in-memory data array, with no external libraries, focusing on raw loop performance in a JavaScript environment.

D3 Starter - Asynchronus

This example demonstrates asynchronous programming in JavaScript using Promise objects and the `setTimeout` API, showing how to handle operations that take time to complete. The code defines a `waitSeconds` function that returns a Promise resolving after a specified delay, then chains `.then()` to log a message once the time has elapsed. Using D3 v6 loaded from a CDN, the page includes explanatory text about asynchronous versus synchronous behavior, with no data visualization or rendering involved—the focus is purely on illustrating the callback and Promise patterns.

Data Fetcher (Asnyc/Await Promise.Then)

This example demonstrates two techniques for fetching remote data in JavaScript and logging the results to the console. The page uses the Fetch API to retrieve a CSV file of CSS named colors from a GitHub gist, with the data returned as raw text. The code contrasts the use of `async`/`await` syntax within an `async function` against the older `Promise` chaining approach via `.then()` methods. Both methods successfully retrieve the same resource, while a plain `console.log` statement prints a separate message to show the order of execution. The example is implemented as a minimal HTML page inside a React project scaffold.

Eloquent JS: Chapter 11

This example visualizes asynchronous programming concepts from Chapter 11 of Eloquent JavaScript using D3 v5. It renders a heading and an SVG canvas that uses d3.forceSimulation to demonstrate how JavaScript handles concurrent tasks. The visualization shows tick intervals with setTimeout, promise resolution ordering, and blocking code execution timing, all represented through animated SVG elements. The code displays timing diagrams showing when setTimeout callbacks and Promise.then handlers execute relative to synchronous code, using D3's force layout to arrange nodes and animated transitions to illustrate event loop behavior over time.

javascript arrays

This example demonstrates a simple JavaScript function that creates an array of sequential numbers using a for loop. The code defines a `range` function that takes a numeric argument, pushes each incrementing value into an empty array, and returns the result. It then logs the output of `range(4)` to the browser console. The visualization relies solely on native JavaScript array methods and console output, with no external libraries or rendering frameworks involved. The example illustrates basic array construction and iteration logic in a minimal, self-contained HTML page.

Gist 4ff85e89516594d9399c15b3c436878f

This example demonstrates JavaScript Promise patterns for asynchronous server communication, showing fetch(), .then(), .catch(), Promise.all/race, custom Promise construction, and async/await syntax. The code samples use the browser's built-in fetch() API against document.URL.toString() to simulate server checks, with console.log output for results and error handling. It also includes a setTimeout-based delay Promise example to illustrate timing control. The gist serves as educational reference material, contrasting Promise chains, custom Promise creation, and sugar-syntax async functions.

Fork of HTML Starter-2

This example demonstrates fetching a CSV file and logging its contents to the browser console. It uses the JavaScript `fetch` API within an async function to retrieve a color dataset from a GitHub Gist URL, then converts the response to text with `response.text()`. The code shows both a modern async/await approach and a commented-out promise-chain alternative. No data visualization is rendered; the focus is on establishing a data-loading pattern for a future visual.

make data async Fork of HTML Starter

This example demonstrates a minimal HTML page that displays a large, centered greeting message. It uses plain CSS for styling and JavaScript to define an asynchronous function that schedules a recurring interval. The page structure is built with standard HTML elements, and the script tag references an external JavaScript file. The visualization relies on basic DOM manipulation and the browser’s native `setInterval` API to manage timing, though no visual updates occur as a result. It serves as a simple template for integrating asynchronous logic with static content.
