no-alert
禁止使用 alert、confirm 和 prompt
JavaScript 的 alert、confirm 和 prompt 函数被广泛认为是侵入性的 UI 元素，应当用更合适的自定义 UI 实现来替代。此外，alert 常在调试代码时使用，在部署到生产环境之前应予以移除。
🌐 JavaScript’s alert, confirm, and prompt functions are widely considered to be obtrusive as UI elements and should be replaced by a more appropriate custom UI implementation. Furthermore, alert is often used while debugging code, which should be removed before deployment to production.
alert("here!");
