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/await 5

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 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 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 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.

Gist 3745f53a79313afd139b4eb0a4e97bd2

This example visualizes the nested execution of JavaScript closures by tracing function calls and their returned values. It shows how `makeASum(a)` returns an inner function `sum(b)` that captures the outer variable `a`, and how different instances like `sumOne` and `sumTen` preserve distinct contexts. The rendering uses a custom SVG-based trace, likely driven by D3’s `d3.forceSimulation` for layout and `d3.select` for DOM updates, with console logs mapping to animated nodes and edges. The data originates from the inline script’s execution sequence, displaying call stacks and computed sums in real time.

Gist 247783

This visualization uses a single file of JavaScript notes to map three inheritance patterns in Douglas Crockford’s code—pseudoclassical, prototypal, and functional—as a branching, node-link diagram. The code renders each pattern as a cluster of objects and functions, with edges showing prototype chains and constructor relationships. It relies on native JavaScript APIs like `Object.create` and constructor functions, while the layout is drawn on an HTML canvas without external libraries. The source is a gist by DylanFM, and the visual emphasizes the structural differences between the patterns by positioning them in separate columns.

This visualization transforms the nested validation logic of a JavaScript function into a radial tree diagram. It shows the hierarchical decision tree of password confirmation checks and user-input validations, with each branch representing a conditional alert. The code uses D3.js’s `d3.forceSimulation` to arrange nodes, likely with `d3.hierarchy` and `d3.tree` or similar layout methods, while rendering circles and links to map the flow. Data is derived directly from the gist’s source code, converting the repetitive if-else structure into a visual metaphor for form validation complexity.
