When working with DOM manipulation, you often get a NodeList from methods like querySelectorAll(), but NodeLists lack many useful array methods. As the creator of CoreUI, a widely used open-source UI library, I’ve encountered this scenario countless times when building interactive components. With over 25 years of JavaScript experience, I can tell you the most efficient and modern solution is to use the spread operator or Array.from(). Both methods are clean, readable, and supported in all modern browsers.
