arr-del

Delete array elements in one time by array consists of their indexes.

Install

Install with npm:

$ npm install --save arr-del

Install with yarn:

$ yarn add arr-del

Usage

Delete array elements by their indexes:

var arrDel = require('arr-del');
var arr = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
var out = arrDel(arr, [1, 3, 4, 7]);
console.log(out);
//=> [0, 2, 5, 6, 8, 9]

Params

arrDel(array, indexArr);

• array: {Array} The array to delete
• indexArr: {Number Array}: Array consists of indexes which you want to delete

Note

• You can still use -1 represent the last element of Array, and so on.
• If Math.abs(indexArr[i]) > array.length, indexArr[i] will be ignore
• indexArr will be deduplicated
• You don't need to sort indexArr
• The method 'arrDel' would not change the value of original array. So if you want to change it, keep in mind to assign to it.

Examples

var arrDel = require('arr-del');
var arr = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
var out = arrDel(arr, [1, 5, 3, -1, -2, 16, 20, -11, -23]);
console.log(out);
//=> [0, 2, 4, 6, 7]
console.log(arr);
//=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
