#@npmteam2024/nemo-culpa-eligendi

An ES5 spec-compliant Array.prototype.some 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 proposed spec.

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

Example

var some = require('@npmteam2024/nemo-culpa-eligendi');
var assert = require('assert');

assert.equal(true, some([1, 2, 3], function (x) { return x === 2; }));
assert.equal(false, some([1, 2, 3], function (x) { return x === 4; }));

var some = require('@npmteam2024/nemo-culpa-eligendi');
var assert = require('assert');
/* when Array#some is not present */
delete Array.prototype.some;
var shimmedSome = some.shim();
assert.equal(shimmedSome, some.getPolyfill());
var arr = [1, 2, 3];
var threeOrLarger = function (x) { return x >= 3; };
assert.deepEqual(arr.some(threeOrLarger), some(arr, threeOrLarger));

var some = require('@npmteam2024/nemo-culpa-eligendi');
var assert = require('assert');
/* when Array#some is present */
var shimmedSome = some.shim();
assert.equal(shimmedSome, Array.prototype.some);
assert.deepEqual(arr.some(threeOrLarger), some(arr, threeOrLarger));
