js-sorting-algorithms
Package provides the javascript implementation of sorting algorithms for array
Features
In terms of usage, the user has the following benefit of using the sorting algorithms:
- Customizable comparer function for the sorting function
- Allow user to sort a sublist of an array starting and ending at the user-defined indices
In terms of supported algorithms for sorting:
- Selection Sort
- Insertion Sort
- Merge Sort
- Quick Sort
- 3-Ways Quick Sort
- Heap Sort
- Shell Sort
Install
Run the following npm command to install
npm install js-sorting-algorithms
Usage
To sort an array "a" using any of the sorting algorithms:
jss.insertionSort(a);
jss.selectionSort(a);
jss.shellSort(a);
jss.mergeSort(a);
jss.quickSort(a);
jss.threeWaysQuickSort(a);
jss.heapSort(a);
Additionally user can specify the range in "a" to do the sorting as well as customized comparer:
var comparer = function(a1, a2){
return a1 - a2;
};
jss.insertionSort(a, lo, hi, comparer);
Sample code is available at playground
Using with nodejs
jssort = require('js-sorting-algorithms');
//====================Simple====================//
var a = [3, 4, 5, 1, 2, 4, 6, 8, 9, 3, 4, 67, 34, 53, 44, 2];
jssort.insertionSort(a);
console.log(a);
//====================Sort with custom comparer function====================//
var a = [[3, 2.3], [4, 3.1], [5, 1.1], [1, 4.2], [2, 4.2], [4, 5.3], [6, 7.4], [8, 5.1], [9, 1.9], [3, 1.2], [4, 3.4], [67, 6.7], [34, 3], [53, 5], [44, 4.2], [2, 0]];
jssort.insertionSort(a, undefined, undefined, function(a1, a2){
return a1[1] - a2[1];
});
console.log(a);
//====================Sort sub-arrray a[3:10] ====================//
var a = [3, 4, 5, 1, 2, 4, 6, 8, 9, 3, 4, 67, 34, 53, 44, 2];
jssort.insertionSort(a, 3, 10);
console.log(a);
