This example demonstrates the JavaScript `Array.prototype.splice` method, showing how it removes an element from an array at a specified index. The code defines an array `[1,2,3,4]` and calls `arr.splice(arr.length-1, 1)` to delete the final item, resulting in `[1,2,3]`. The visualization presents this operation as a concise educational snippet, highlighting the method’s signature and the dynamic calculation of the index based on the array’s current length. No external libraries are used; the example relies solely on native JavaScript array operations.

This example shows a JavaScript function called `copyMachine` that duplicates an array’s contents a given number of times. The code uses a `while` loop and the spread operator `[...arr]` to append copies of the original array to itself, then stores the result in `newArr`. It demonstrates array mutation and reassignment within a loop, logging the final duplicated array to the console via `console.log`. The function handles a numeric `num` parameter, decrementing it until the loop ends, and returns the expanded array. No external libraries or visualization APIs are used; it is plain JavaScript array manipulation.

This example demonstrates a manual JavaScript algorithm for rotating the elements of an array-like object, shifting the last item to the front while moving each preceding item one position backward. It uses no external libraries, relying on native object property access and assignment via `Object.keys()` and array index notation. The code defines a hardcoded sequence of four swap operations, storing the final value in a temporary `aux` variable to preserve it during reassignment, then logs the updated object to the console after each call. The data originates from an `images` object with an unspecified number of keys, though the logic assumes at least four properties to function correctly.

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.

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.

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.

JavaScript Arrays

This example demonstrates the JavaScript `Array` API and the behavior of the `push` method, specifically how a function named `range` initializes an array with a single element, `0`, and returns it. The visualization, which is purely code-based without any graphical output, uses the standard JavaScript runtime and console logging to display the result of calling `range(5)`. It shows the creation of an array literal, the `push` operation, and the commented-out example of adding a third element to a separate array. The code relies on the built-in `console.log` function to output the arrays to the developer console.

This example demonstrates a simple JavaScript routine that removes all spaces from each of three strings in a loop, printing the cleaned result alongside its index. The code defines a utility object with a method that splits a string on spaces, filters out empty entries, and concatenates the remaining characters. It uses no external libraries, relying only on native JavaScript string and array methods, such as `split` and a `for` loop, to process the data. The output is logged to the console, showing the transformation for each iteration.

hello world

This example displays a JavaScript array after using the splice method to remove elements. It imports a family data object from a separate module, though the array displayed is not derived from that object. The page uses basic HTML and CSS to center the output text, with JavaScript manipulating the array and writing the result into a paragraph element. The visualization is minimal, showing only the array contents as text on a blank page.
