ES6 Proxy magic for arrays

This example demonstrates how a plain JavaScript object with numeric keys and a `length` property can be made to behave like a real array. It uses an ES6 `Proxy` to intercept property access and assignment, delegating missing methods to `Array.prototype` and automatically updating the `length` value. The code explicitly handles length changes by deleting excess properties and adjusting the stored length. The demonstration uses the `emulateArray` function from the gist to wrap a simple three-element object, showing array-like behavior without subclassing `Array`.

JS Class proto Proxy

This example demonstrates a JavaScript class that uses a Proxy to create a counter with automatic default values and type enforcement. The `Counter` class wraps a plain object in a `Proxy`, intercepting `get` operations to initialize missing keys to zero and `set` operations to reject non-numeric values. It provides iterator methods like `entries`, `sortedEntries`, and `sorted` for retrieving and ordering the counted data, using standard JavaScript iterators and `Object.entries`. The code relies solely on native JavaScript APIs, including the `Proxy` traps `get`, `set`, `has`, `ownKeys`, and `getOwnPropertyDescriptor`.

JS tips

This example demonstrates common JavaScript programming patterns and techniques through concise code snippets. It covers assignment shortcuts, existential checks, JSONP implementation with jQuery’s `getJSON`, a polyfill for `Object.create`, function proxying, reserved words, and the `array.indexOf` method. The code is presented as a gist, showing practical APIs like `Object.create`, `func.apply`, and `Array.indexOf`, with comments explaining each pattern and equivalent syntax in CoffeeScript.

JS Arrays

This example demonstrates the basic concept of JavaScript arrays. It shows how to create an empty array and how to add elements to the end of the list using the `push` method, as well as how to check the number of elements with the `length` property. The code is plain JavaScript executed in the browser without any external libraries or data sources, serving as a simple educational snippet for array manipulation.

please copy into repo

This example demonstrates array manipulation techniques in JavaScript, implementing utility functions such as `indexOf`, `sum`, `remove`, `append`, `truncate`, and `findAllOccurrences`. The code defines an object with methods that operate on arrays, including custom implementations for finding element positions, calculating sums, copying arrays without mutations, and detecting duplicates. The visualization relies on plain JavaScript array methods and loops, with the `exports` pattern exposing the functions for use in browser or Node environments. The source data consists of hardcoded test arrays, and the rendering approach uses no external libraries or graphical APIs.

A set of pure and immutable ES2015 functions aimed to make functional JavaScript more idiomatic.

This example presents a collection of pure, immutable ES2015 utility functions for idiomatic functional JavaScript. It includes array operations such as `combine`, `compact`, `difference`, and `intersection`, object helpers like `merge` and `toMap`, math functions (`min`, `max`, `sum`, `product`), and function decorators including `curry`, `once`, `maybe`, and `pipeline`. The code relies on native JavaScript features like `Array.prototype.includes`, `Set`, `Map`, `Object.assign`, and spread syntax. No external libraries or data sources are used; the gist demonstrates standalone, reusable functional patterns.

JavaScript Arrays

This example demonstrates common JavaScript array methods for data manipulation and transformation. The code defines a `range` function that creates a numeric array, then uses commented-out examples of `forEach`, `filter`, `sort`, and `map` to show how these operations work. The active portion creates an array of key-value objects and uses `Array.prototype.reduce` to convert it into a single object. The example relies entirely on native JavaScript APIs and is meant to be explored through browser DevTools console output, with no external libraries or visual rendering involved.

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 Arrayds

This example presents a minimal demonstration of JavaScript array manipulation in a web page. It creates an array containing the strings "a" and "b", appends the number 3 using the `push` method, and logs the resulting array to the browser console via `console.log`. The page uses no external libraries, relying solely on native JavaScript within an HTML document. A large styled message area is defined but left empty, while the actual visualization occurs in the developer console output.
