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 deleteindexArr
: {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]
