This example demonstrates a JavaScript array manipulation that generates all possible single-step neighbors for a four-digit lock combination. It creates two variations for each digit: one decrementing the value (with 0 wrapping to 9) and one incrementing it (with 9 wrapping to 0), storing all eight resulting arrays in a `neighbors` list. The code uses standard JavaScript array methods like `forEach` and `slice`, along with a ternary operator for edge-case wrapping, to construct the neighbor variations. The output, logged via `console.log`, shows a matrix of four-element arrays representing every adjacent combination state.

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 visualization prints an alternating checkerboard pattern of spaces and hash symbols to the console, using standard JavaScript string concatenation and a nested `for` loop structure. The outer loop controls each row, while the inner loop builds the pattern by checking whether the row and column indices are even or odd. The code defines a fixed grid size of 8, generates each line into a string variable, and logs it with `console.log` before resetting the string for the next iteration. No external libraries are used; it relies solely on core JavaScript syntax and the console API.

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.

JavaScript Array

This example demonstrates JavaScript array operations, focusing on how to create and manipulate arrays in the browser console. The code defines a `range` function that generates an array of numbers from 0 to 4, then applies various array methods including `forEach`, `filter`, and `sort`. The final visible output shows how `.sort()` combined with `.reverse()` reorders the array `[0, 9, 1, 84, 23, 6]`, logging the reversed sorted result to the console. The visualization uses a large text message to display the result, with the logic implemented through raw JavaScript array prototypes rather than any external libraries.

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.

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.

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.

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.
