Modular standard library for JavaScript. Includes polyfills for ECMAScript up to 2019: promises, symbols, collections, iterators, typed arrays, many other features, ECMAScript proposals, some cross-platform WHATWG / W3C features and proposals like URL. You can load only required features or use it without global namespace pollution.

Example:

import 'care-js'; // <- at the top of your entry point
 
Array.from(new Set([1, 2, 3, 2, 1]));          // => [1, 2, 3]
[1, [2, 3], [4, [5]]].flat(2);                 // => [1, 2, 3, 4, 5]
Promise.resolve(32).then(x => console.log(x)); // => 32

You can load only required features:

import 'care-js/features/array/from'; // <- at the top of your entry point
import 'care-js/features/array/flat'; // <- at the top of your entry point
import 'care-js/features/set';        // <- at the top of your entry point
import 'care-js/features/promise';    // <- at the top of your entry point
 
Array.from(new Set([1, 2, 3, 2, 1]));          // => [1, 2, 3]
[1, [2, 3], [4, [5]]].flat(2);                 // => [1, 2, 3, 4, 5]
Promise.resolve(32).then(x => console.log(x)); // => 32

Or use it without global namespace pollution:

import from from 'care-js-pure/features/array/from';
import flat from 'care-js-pure/features/array/flat';
import Set from 'care-js-pure/features/set';
import Promise from 'care-js-pure/features/promise';
 
from(new Set([1, 2, 3, 2, 1]));                // => [1, 2, 3]
flat([1, [2, 3], [4, [5]]], 2);                // => [1, 2, 3, 4, 5]
Promise.resolve(32).then(x => console.log(x)); // => 32

It's a global version (first 2 examples), for more info see care-js documentation.
