This example visualizes the process of refactoring a JavaScript function that returns the largest number from each sub-array in a nested array. It shows three successive code versions—using `Math.max.apply`, the spread operator with `Math.max(...arr[i])`, and a manual nested loop—to achieve the same result. The code relies on standard JavaScript array methods and the `Math.max` API, with no external libraries. The visualization likely renders the code side-by-side or as a sequence, highlighting syntax differences and algorithmic approaches. The data source is the hardcoded sample array passed to each function call, demonstrating how the output remains identical across implementations.

This example visualizes the logic of a function called `slasher` through two alternative implementations. It shows how array slicing and splicing can be used to return a truncated array, with the first version mutating the original via `splice` and the second using `slice` to create a new array. The code renders the function definitions and their invocation results as a static code display, relying on no external libraries or graphics APIs—the visualization is purely textual, presenting the JavaScript source and its output. The data source is the embedded code itself, highlighting the difference between mutating and non-mutating array methods.

JavaScript Arrays

This example demonstrates JavaScript array manipulation techniques, including `forEach`, `filter`, `sort`, `map`, and `reduce`, using a generated range of numbers and an array of key-value objects. The code highlights sorting differences between default lexicographic ordering and numeric sorting with a comparator, as well as using the `ascending` helper from d3. It also shows how `reduce` can transform an array into an object or sum values. The visualization is a code-based teaching tool with no visual output, focusing on logged results in the console.

JavaScript Arrays

This example demonstrates fundamental JavaScript array operations, including range generation, sorting, filtering, mapping, and reducing, using a variety of data structures. The code creates a numeric range with a custom `range` function, sorts an array of numbers with a comparator, and applies transformations like doubling values and summing elements. It also defines an array of key-value objects. All operations are logged to the console, with results visible in the browser’s developer tools. The example imports the `ascending` helper from D3, though it is not actively used, and runs within a minimal HTML page with no visual output.

JavaScript Arrays

This example demonstrates the fundamental array methods in JavaScript, including `range`, `filter`, `map`, `sort`, `forEach`, and `reduce`. The code uses D3 v6’s `ascending` and `decending` imports to properly sort arrays, while also showcasing custom comparator functions. It works with a simple generated range of numbers and a small dataset of key-value entries, logging results to the console. The page renders only the static title “JavaScript Arrays” with no visual output, focusing entirely on algorithmic array manipulation.

arrays

This example demonstrates fundamental JavaScript array operations through console logging, including iteration, filtering, sorting, mapping, and reducing. It shows a custom `range` function, a sorting comparator for numbers, and how to build objects from array entries using `reduce`. The code imports `ascending` and `descending` from D3 to illustrate library-based sorting, and relies on D3 version 7.3.0 for these utilities. The visualization itself is minimal—a single HTML page with a large styled message—while the core content lives in the script’s output.

JavaScript Arrays

This example demonstrates common JavaScript array operations using plain code and D3’s `ascending` comparator. It shows how functions like `range`, `forEach`, `filter`, `map`, `reduce`, and `sort` transform arrays, including sorting numeric values correctly and grouping entries by key. No visual output is rendered; the code logs intermediate results to the console. The example uses the `d3` library’s `ascending` function for stable sorts, building a practical reference for array manipulation basics.

Arrays

This example showcases JavaScript array manipulation techniques, including `forEach`, `filter`, `sort`, and `reduce`. The code logs a computed sum from a hardcoded array `[1, 3, 5, 10, 30]` using the `reduce` method, while commented-out lines demonstrate additional array operations. It renders no visual output; instead, it serves as a minimal HTML page with embedded JavaScript, illustrating functional programming concepts for educational purposes. The example relies solely on native JavaScript APIs without external libraries or data sources.

JavaScript Arrays

This example demonstrates a simple JavaScript array manipulation exercise using D3.js v7. It builds a custom range function to generate an array of numbers, then explores array methods like `forEach`, `filter`, `sort`, `map`, and `reduce` through commented code examples. The active portion sorts an array of objects by their `key` property using D3’s `ascending` comparator. The visualization gallery entry primarily serves as a code tutorial rather than a visual output, with no graphical rendering or data source involved.
