This is a playground to test JavaScript. It runs a completely standard copy of Node.js on a virtual server created just for you. Every one of npm’s 300,000+ packages are pre-installed, so try it out:
require("browserslist");
const { matchesUA } = require('browserslist-useragent');
// user agent strings
const UA_ios_saf_10_1 = 'Mozilla/5.0 (iPhone; CPU iPhone OS 10_1 like Mac OS X) AppleWebKit/602.2.14 (KHTML, like Gecko) Version/10.0 Mobile/14B72 Safari/602.1';
const UA_ios_saf_10_3_1 = 'Mozilla/5.0 (iPhone; CPU iPhone OS 10_3_1 like Mac OS X) AppleWebKit/603.1.30 (KHTML, like Gecko) Version/10.0 Mobile/14E8301 Safari/602.1';

// returns `true` for all except `ios_saf >= 10.1`
console.log(
