// Test: const urls = [ "https://website.com/coolpage/938921/", "https://www.website.com/coolpage/938921/", "http://website.com/coolpage/938921/", "https://website.com/coolpage/938921/", "https://website.com/coolpage/938921/?awesome=1", "https://website.com/coolpage/938921?awesome=1", "https:///website.com//coolpage//938921//" ]; for (let i = 0; i < urls.length; i++) { const u = getBaseUrl(urls[i]); console.log(`${i}: ${u}`); }
