Why is DOM manipulation expensive?
When you’re dealing with a client-side application, you quickly face one issue: DOM manipulation is expensive. If your application is big or very dynamic, the time spent in manipulating DOM elements rapidly adds up and you hit a performance bottleneck. If the model doesn’t change, it won’t touch the DOM.
How can I practice DOM manipulation?
