This example extends JavaScript’s Array prototype with a `count` method that returns the number of occurrences of a given value within an array. The code uses `Array.prototype.filter` to test each element against the target value and measures the resulting array’s length. It demonstrates a simple, reusable utility for frequency analysis without relying on external libraries or data sources.

JS Array Basics

This example demonstrates fundamental JavaScript array operations through console-logged examples. It shows how to generate a numeric range and apply array methods including filter, forEach, map, sort, and reduce. The code also illustrates how reduce can transform an array into an object by accumulating key-value pairs. All operations are performed in plain JavaScript with no external libraries or data sources, using a hardcoded array of numbers and sample entries.

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.

JS Bin

This example counts character frequency in a long string of text and outputs a sorted array of characters with their occurrence counts. The code uses JavaScript's `reduce` method to build a frequency object, then sorts the result in descending order using a custom `compareNumbers` function. The data source is a hardcoded string of lowercase letters and underscores. The final output is logged to the console via `console.log`, showing the sorted array in descending order by frequency.

javascript arrays

This example demonstrates a simple JavaScript function that creates an array of sequential numbers using a for loop. The code defines a `range` function that takes a numeric argument, pushes each incrementing value into an empty array, and returns the result. It then logs the output of `range(4)` to the browser console. The visualization relies solely on native JavaScript array methods and console output, with no external libraries or rendering frameworks involved. The example illustrates basic array construction and iteration logic in a minimal, self-contained HTML page.

JS Arrays

This example demonstrates JavaScript array manipulation using a custom `range` function to generate an array of ten numbers, then mapping each element to an object containing the original number and its double. The code logs the resulting array of objects to the browser console. It uses the native array methods `push`, `map`, and `forEach`, with additional commented-out examples showing `filter`, `sort`, and `reverse` operations. The visualization is purely text-based, with output appearing in the developer console rather than on the page.

Java Script

This example demonstrates basic JavaScript array operations in a minimal HTML page. The code creates a range of numbers from 0 to 9 using a custom `range` function, logs each value to the console, and then filters for even numbers before sorting. It uses vanilla JavaScript with the `forEach` and `filter` array methods, plus `console.log` for output. The page includes CSS styling for a large centered message but displays no visual data, focusing instead on console-based programming fundamentals.

Javascript Arrays

This example demonstrates JavaScript array methods by logging transformations of a hardcoded dataset to the browser console. It uses `filter` to select even numbers, `sort` with a custom comparator and the imported `ascending` function from d3 to order values, and `map` to create objects containing each number and its double. A `reduce` operation converts an array of key-value objects into a single object keyed by the original keys. The example runs entirely in the console without producing any visual output on the page.

js array

This example demonstrates a JavaScript array created with a custom `range` function, which generates numbers from 0 to 9. The code uses plain JavaScript (no external libraries) to populate an array via a `for` loop, then iterates through it using `forEach`, logging each element to the console with `console.log`. It shows a simple array construction and iteration pattern in a bare HTML page.
