array.prototype.filter's Introduction

array.prototype.filter

An ES5 spec-compliant Array.prototype.filter shim/polyfill/replacement that works as far down as ES3.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec.

Because Array.prototype.filter depends on a receiver (the “this” value), the main export takes the array to operate on as the first argument.

Example

var filter = require('array.prototype.filter');
var assert = require('assert');

assert.deepEqual(filter([1, 2, 3], function (x) { return x >= 2; }), [2, 3]);
assert.deepEqual(filter([1, 2, 3], function (x) { return x <= 2; }), [1, 2]);

var filter = require('array.prototype.filter');
var assert = require('assert');
/* when Array#filter is not present */
delete Array.prototype.filter;
var shimmedFilter = filter.shim();
assert.equal(shimmedFilter, filter.getPolyfill());
var arr = [1, 2, 3];
var isOdd = function (x) { return x % 2 !== 0; };
assert.deepEqual(arr.filter(isOdd), filter(arr, isOdd));

var filter = require('array.prototype.filter');
var assert = require('assert');
/* when Array#filter is present */
var shimmedFilter = filter.shim();
assert.equal(shimmedFilter, Array.prototype.filter);
assert.deepEqual(arr.filter(isOdd), filter(arr, isOdd));

Error not loaded 'define-properties'

I submitted this bug report on the bootstrap project as well

I'm using aurelia v1.0, bootstrap 5.0.1
I ran yarn upgrade and am now getting an error not loaded: define-properties.
I've been able to track the error down to array.prototype.filter which is installed only by bootstrap 5.0.1
I'm guessing that the error is in the first line of index.js

'use strict';

var define = require('define-properties');
var RequireObjectCoercible = require('es-abstract/2020/RequireObjectCoercible');
var callBound = require('call-bind/callBound');

var implementation = require('./implementation');
var getPolyfill = require('./polyfill');
var polyfill = getPolyfill();
var shim = require('./shim');

var $slice = callBound('Array.prototype.slice');

// eslint-disable-next-line no-unused-vars
var bound = function filter(array, callbackfn) {
	RequireObjectCoercible(array);
	return polyfill.apply(array, $slice(arguments, 1));
};
define(bound, {
	getPolyfill: getPolyfill,
	implementation: implementation,
	shim: shim
});

module.exports = bound;

I have run npm define-properties but to no avail.

I have also cloned the array.prototype.filter project and can't even get it to run the tests

The project seems to have been updated a few days ago, but I can't find the previous version.

I should add that my project was running perfectly until this morning.
