This example visualizes the flow of a sequential asynchronous function, showing how each awaited promise resolves in a chain before the next begins. The code defines an `async` function with three sequential `await` calls—`doA()`, `doB(a)`, and `doC(b)`—where each step passes its result into the next. The visualization maps this dependency chain, highlighting the blocking nature of each await and the data handoff between stages. It relies on JavaScript’s native `async`/`await` syntax, with no external libraries, and renders a linear timeline of the function’s execution order.

Async/await 6

The example shows an asynchronous JavaScript flow where the program awaits one operation, then runs two independent tasks in parallel via `Promise.all`. The code displays `doA()`, followed by `doB(a)` and `doC(a)` as the two concurrent calls after the first result resolves. It uses native `async`/`await` syntax with `Promise.all()` to coordinate these dependent and independent steps. No rendering library or data source is visible; the visualization focuses purely on the sequence and branching of these promises.

Async/await 4

This example visualizes JavaScript promise chains as animated, interactive force-directed graphs using D3’s `d3.forceSimulation`. The code shows two parallel promise sequences—one resolving `doA`, `doB`, and `doC` sequentially, and another matching a separate `do()` function—each drawn as nodes and links on a canvas. The graph uses D3’s force layout to position nodes, with links updating in real time as promises resolve. The rendering relies on D3’s canvas API, and the data source is the hardcoded promise structure from the gist, not external input. The animation communicates the order and dependency of asynchronous calls.

Async/await 3

This example visualizes the nested callback structure of an asynchronous JavaScript function as a branching tree diagram. It shows how sequential `doA`, `doB`, and `doC` calls with error-handling callbacks create a multi-level flow. The visualization uses a force-directed layout from D3’s `d3.forceSimulation` to position nodes, with links rendered as curved paths. The code snippet from the gist is the direct source, and the rendering approach highlights the increasing depth of callbacks as the program progresses.

async-for-each

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.

Basic promise structure

This example demonstrates a basic promise chain controlling sequential execution of asynchronous functions triggered by a user click. It shows how JavaScript Promises manage ordered flow, with each function logging its completion status before resolving. The code uses native Promise constructors and the `.then()` method to chain `function1()`, `function2()`, and `function3()` after an initial `initialFunction()`. The interaction is tied to a jQuery click handler on `#loadAudio`, and all resolutions print colored console messages via `console.log`. No data sources or visual outputs are involved; the focus is purely on the control-flow pattern.

Async/await 2

A force-directed network graph visualizes the branching control flow of an `if/confirm` dialog, showing the sequential execution paths after user confirmation. The JavaScript example uses D3.js's `d3.forceSimulation` for physics-based layout and `d3.geoPath` for rendering curved edges that trace possible program states. Nodes represent code checkpoints, while animated links highlight the active branch as the simulation converges. The source data comes from the inline `async-2.js` snippet, with the graph emphasizing how asynchronous code transitions between confirmed and canceled states.

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.

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.
