— Virtual dom is a hype-word


Any framework is a "switcher", it switches nodes in the DOM tree, new appear, old disappear. when it happens, user should re-bind to new DOM targets, or the lib do nothing or throw errors in console.

— So, i see only one side effect - you work with detached DOM node.

— Okay thanks👍

— That's not a side effect :P

— If you do everything absolutly right, side effect doesnt exists🤤

— Ive had some discussion recently..

— Some time ago I read an article about jsperf not being a reliable way to compare/check js performance.

When I find ill post it here.
