array-remove-if

Remove all array elements that satisfy the given condition.

Installation

Add dependency:

npm install array-remove-if 

Then require the module:

require('array-remove-if');

This module adds the removeIf method to Array's prototype, and does not export anything.

Usage

Syntax:

var removedElements = array.removeIf(callback);

Parameters:

Return value: A new array with the removed elements.

Examples

Remove even numbers:

var x = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
var y = x.removeIf(e=>e % 2 == 0);
// x = [1, 3, 5, 7, 9]
// y = [2, 4, 6, 8, 10]

Remove words containing 'r':

var x = ['collect', 'enormous', 'drawer', 'art', 'thought', 'burly', 'special', 'claim', 'troubled', 'aboard'];
var y = x.removeIf(e=>e.indexOf('r') > -1);
// x = ['collect', 'thought', 'special', 'claim']
// y = ['enormous', 'drawer', 'art', 'burly', 'troubled', 'aboard']

Remove all elements which are not a number:

var x = [0, 1, 'string'];
var y = x.removeIf(e=>typeof e !== 'number');
// x = [0, 1]
// y = ['string']
