This example detects assignments to `window.document.domain` inside inline JavaScript and removes them from a saved CNN news page. It parses each inline script into an abstract syntax tree using Babylon, traverses the tree with Babel’s `traverse`, and filters `AssignmentExpression` nodes where the computed key is the literal `'domain'` and the object is `document`. Modified scripts are regenerated with `babel-generator`, and the updated HTML is written back to disk using `fs-extra`. The code reads the original page with Cheerio and writes the result to `mod.html`.

JS Bin

This example demonstrates JavaScript destructuring of objects through a side-by-side comparison of original source code and the compiled output. The `index.html` file contains two script blocks: the first shows transpiled ES5 code using `var` declarations and manual property access, while the second shows the original ES6 source with `const` and destructuring assignment. The code logs names from objects to the console, illustrating how ES6 destructuring patterns translate into traditional variable assignments. The visualization uses plain HTML and JavaScript with no external libraries.

2017-07-25: Swimming In A Ocean Of JavaScript. Using Nodejs, Electron And Chrome To Preserve The Web

This example demonstrates a Node.js toolkit for web archiving, showing how to parse, stream, and generate WARC and CDXJ files to preserve web content. It uses the `cdxj` library to read CDXJ indexes asynchronously, the `node-warc` parser with event listeners for streaming WARC records, and a configuration object for the `squid` crawler that controls Chrome via its WebSocket API. The code highlights handling HTTP/2 limitations in archives and supports features like page-same-domain crawling and auto-scrolling.

Gist 16d0e6050f60256517db942d1fe29703

This example demonstrates a technique for remotely fetching and inspecting CSS stylesheets, particularly extracting image URLs from `srcset` attributes and resolving cross-origin stylesheet rules. The code uses the Fetch API with a CORS proxy to retrieve stylesheet contents, then parses `srcset` strings with a custom regular expression to collect image candidates. It also leverages `document.styleSheets`, `cssRules`, and a temporary `<style>` element to access rule data, while caching processed elements in a `WeakSet` to avoid duplication. The visualization output is logged to the console, showing the collected stylesheet rules and image URLs from the current page.

Internet Archive Incorrectly Wrapping Valid HTML

This example demonstrates how the Internet Archive’s Wayback Machine inserts its banner and analytics scripts into an archived page, wrapping a Polymer web component’s `<dom-module>` and its script in unexpected ways. The archived HTML shows the original valid structure disrupted by added script tags and a `textarea` element containing code, breaking the component’s expected parsing. It uses Polymer’s element registration and observers, plus XMLHttpRequest for fetching data, highlighting the mismatch between archived and original HTML.

https://jsfiddle.net/developit/q435c6mL/

This example implements a live DOM audit logger that intercepts and records modifications to page elements as they occur. It demonstrates real-time logging of property changes (textContent, innerHTML, className) and node insertions/removals, displaying a formatted trail of each operation with previous and current values. The visualization uses the DOMAuditLogger library, which patches native Element and Node prototype methods to capture events, and renders the audit entries in a scrolling view with color-coded message types.

Making Javascript faster

This example presents a markdown document that compiles performance guidelines for JavaScript, sourced from a gist by GerHobbelt and linked to jsPerf benchmarks. The text explains optimization techniques such as using IIFEs over nested functions, avoiding the `arguments` object, and preferring `that` instead of `bind`. It describes the content without a graphical interface, serving as a static textual reference for developers.

Eloquent JS: Chapter 5

This example displays the output of four JavaScript exercises from Chapter 5 of Eloquent JavaScript, all run in the browser console. It shows array flattening using `reduce`, a custom `loop` function, an `every` predicate implementation with `filter`, and a `dominantDirection` function that uses `countBy` and `characterScript` to classify text direction. The code relies on the standard JavaScript array methods and the predefined `SCRIPTS` dataset. The page renders only static text and styled body text via CSS, with results logged to the console.

JavaScript Exp

This example presents a minimal web page that checks the integration of JavaScript and CSS within an HTML document. It displays a large, centered "Hello HTML!" message, demonstrating basic styling applied via a CSS class. The code uses vanilla JavaScript to log the Document Object Model (DOM) to the browser console, illustrating how to access and inspect the page structure programmatically. This serves as a bare-bones starting point for web development, with a linked reference to a separate React-based starter project.
