Onde posso encontrar documentação ou suporte para a API?

(function () { const YEAR = new Date().getFullYear(); const endDate = new Date(YEAR, 6, 19); // July 19 const today = new Date(); today.setHours(0, 0, 0, 0); endDate.setHours(0, 0, 0, 0); const oneDay = 1000 * 60 * 60 * 24; const daysLeft = Math.ceil((endDate - today) / oneDay); const text = daysLeft > 0 ? daysLeft + " " + (daysLeft === 1 ? "Day left" : "Days left") : "Last day"; document.querySelectorAll(".days-left-modal").forEach(function (el) { const target = el.querySelector(".elementor-heading-title") || el.querySelector(".elementor-widget-container") || el; target.textContent = text; }); })();
