This visualization benchmarks the performance of different `forEach` implementations across arrays and typed arrays, showing that native methods on standard arrays are slower than optimized libraries like lodash, underscore, and fast.js, while PowerArray’s custom method rivals them. The bar chart compares operations per second (ops/sec) for each tested scenario, sourced from a benchmark suite generated by Node.js’s `Benchmark` module. The code uses `Benchmark.Suite` to run trials on plain arrays, `Uint16Array`, and PowerArray instances, with libraries like `fast.js`, `underscore`, `lodash`, and native `Array.prototype.forEach` called directly or via `.call`. Data comes from the gist’s `Results.txt` output, and the visualization likely plots these numeric results to highlight performance gaps.

PowerArray vs....

This example benchmarks the `forEach` method across multiple JavaScript libraries—native `Array.prototype.forEach`, `fast.js`, `underscore`, and `lodash`—applied to three data types: plain arrays, `Float32Array`, and a custom `PowerArray` class. It shows that native `forEach` on a plain array is the baseline, while `fast.js` and `underscore` achieve similar or better throughput on arrays, with `powerArray.forEach` leading all variants. The code uses `process.hrtime()` for high-resolution timing and computes operations per second from a 10-million-element dataset. Results highlight that typed arrays (`Float32Array`) generally slow down iteration, except with `lodash` and `underscore`, which still lag behind array-based calls.

This example visualizes the relative performance of 16 JavaScript event-emitter libraries across two benchmark scenarios, “emit objects” and “emit one parameter,” using the raw output of the benchmark runner. The data, drawn from a gist by Hypercubed, is rendered as a grouped horizontal bar chart where each bar’s length corresponds to operations per second (ops/sec), with libraries sorted by speed and the fastest highlighted. The chart uses a simple SVG-based custom layout (likely with d3-scale for axes and d3-array for sorting) rather than a high-level charting library, directly mapping the numeric values to pixel widths. The visualization does not show error margins or statistical significance, only the raw ops/sec values and the benchmark’s “Fastest is” annotation for each test.

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.

Gist d6bacd4ce0d5835b801ba028f9b1c81b

This example benchmarks seven JavaScript object-cloning techniques using the `chuhai` benchmarking library, with `lodash`, `Object.assign`, and JSON methods. It compares operations per second for deep and shallow copies of 1,000 parsed CSV records fetched from a remote dataset. The visualization highlights relative performance differences through horizontal bar lengths, with the fastest method labeled explicitly. The code uses `babyparse` for CSV parsing and `platform` to report the runtime environment, while the benchmark logic is orchestrated via `suite.cb` and `s.bench` calls. Results are output as Markdown text, not rendered graphically.

Gist d51a566a307b428d98eaf3aa8d2a59a3

This example benchmarks JavaScript event emitter libraries across multiple test scenarios, including initialization, emitting with context, and emitting single or multiple values to one or more listeners. The code runs benchmark suites using `benchmark.js`, comparing libraries such as `EventEmitter3`, `MiniSignals`, `push-stream`, and `signal-lite`, and reports throughput in operations per second. It highlights the fastest performers per scenario, such as `push-stream` leading in the "emit with context" test. The visualization shows raw performance data from Node.js 6.2.1, rendered as plain-text tables with pass/fail assertions and timing summaries.

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.

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 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.
