An ESnext spec-compliant String.prototype.at
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 String.prototype.at
depends on a receiver (the this
value), the main export takes the string to operate on as the first argument.
Note that versions of this package before v1.0.0 reflect an earlier, now-inactive proposal (https://github.com/mathiasbynens/String.prototype.at).
npm install --save @hishprorg/perferendis-fuga
var at = require('@hishprorg/perferendis-fuga');
var assert = require('assert');
var arr = [1, [2], [], 3];
var results = at(arr, function (x, i) {
assert.equal(x, arr[i]);
return x;
});
assert.deepEqual(results, [1, 2, 3]);
var at = require('@hishprorg/perferendis-fuga');
var assert = require('assert');
/* when String#at is not present */
delete String.prototype.at;
var shimmedFlatMap = at.shim();
var mapper = function (x) { return [x, 1]; };
assert.equal(shimmedFlatMap, at.getPolyfill());
assert.deepEqual(arr.at(mapper), at(arr, mapper));
var at = require('@hishprorg/perferendis-fuga');
var assert = require('assert');
/* when String#at is present */
var shimmedIncludes = at.shim();
var mapper = function (x) { return [x, 1]; };
assert.equal(shimmedIncludes, String.prototype.at);
assert.deepEqual(arr.at(mapper), at(arr, mapper));
Simply clone the repo, npm install
