TypeScript Sorting Algorithms

A collection of sorting algorithms implemented in TypeScript.

Installation

npm i @mfx2/sorting-algorithms-utility

const sorter = new Sorter();
const unsortedArray = [64, 34, 25, 12, 22, 11, 90];

// Using Bubble Sort
const bubbleSorted = sorter.bubbleSort([...unsortedArray]);
console.log('Bubble Sort:', bubbleSorted);

// Using Merge Sort
const mergeSorted = sorter.mergeSort([...unsortedArray]);
console.log('Merge Sort:', mergeSorted);

// Using Quick Sort
const quickSorted = sorter.quickSort([...unsortedArray]);
console.log('Quick Sort:', quickSorted);

// Using Heap Sort
const heapSorted = sorter.heapSort([...unsortedArray]);
console.log('Heap Sort:', heapSorted);

// Using Selection Sort
const selectionSorted = sorter.selectionSort([...unsortedArray]);
console.log('Selection Sort:', selectionSorted);

// Using Insertion Sort
const insertionSorted = sorter.insertionSort([...unsortedArray]);
console.log('Insertion Sort:', insertionSorted);

Available Sorting Algorithms

• Bubble Sort: bubbleSort(array: number[]): number[]
• Merge Sort: mergeSort(array: number[]): number[]
• Quick Sort: quickSort(array: number[]): number[]
• Heap Sort: heapSort(array: number[]): number[]
• Selection Sort: selectionSort(array: number[]): number[]
• Insertion Sort: insertionSort(array: number[]): number[]

Each sorting method takes an array of numbers as input and returns a sorted array.

Performance

The time complexity of these sorting algorithms varies:

• Bubble Sort: O(n²)
• Merge Sort: O(n log n)
• Quick Sort: O(n log n) average case, O(n²) worst case
• Heap Sort: O(n log n)
• Selection Sort: O(n²)
• Insertion Sort: O(n²)
