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 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.

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 demonstrates a nested-loop algorithm for removing duplicate values from an array, highlighting the logic behind the process. The code defines `removeDuplicatesNested`, which compares each element against every other element using a nested `for` loop, tracking potential matches with a `duplicateFound` flag. It pushes non-duplicate items into a new `returnArray`, though the inner loop’s condition incorrectly checks `returnArray` instead of the original `array`, leading to flawed duplicate detection. The implementation relies solely on standard JavaScript array methods and loops, with no external libraries or rendering APIs. The data source is the input array passed directly to the function, and the visualization focuses on the control flow and comparison steps rather than graphical output.

This example demonstrates a JavaScript implementation of the Fisher–Yates shuffle algorithm, providing two distinct array manipulation methods. The `shuffle()` function returns a new, shuffled copy of the original array without modifying it, while `permShuffle()` permanently rearranges the elements in place. The code extends the native `Array.prototype` with these custom methods, using modern JavaScript syntax including spread operators and destructuring assignments for element swapping. A usage example with a five-element array illustrates both behaviors, showing the original array preserved after copying and altered after permanent shuffling. The implementation relies solely on core JavaScript array operations and the built-in `Math.random()` function.

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.

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.

This example shows a JavaScript function that counts down from a given number and logs each value as either “par” (even) or “impar” (odd) to the console. It uses a `while` loop with a modulo (`%`) operator to test each integer against `0` and then prints the corresponding label. The function `func(10)` is called to process numbers from 10 down to 1, producing a simple text-based output without any graphical or charting libraries. The data source is the hardcoded initial value passed as an argument.

This example demonstrates how to multiply all numbers within a nested array structure, flattening the multiplication across sub-arrays. The code uses nested `for` loops to iterate through each inner array, updating a running `product` variable. A test case with `[[1,2],[3,4],[5,6,7]]` is provided at the end, showing the expected result of 5040. The visualization highlights the logic of nested iteration and cumulative multiplication, with the data source being the hardcoded test array. No external libraries or rendering APIs are used, as the focus is on the algorithmic pattern in plain JavaScript.
