Deep copy or shallow copy?

What rupert said. I’ve also done it by adding console.time('render') and console.timeEnd('render') at carefully chosen spots in the compiled JS… For example around this block:

github.com

elm/browser/blob/1d28cd625b3ce07be6dfad51660bea6de2c905f2/src/Elm/Kernel/Browser.js#L49-L52


      
          				var nextNode = view(model);
          				var patches = __VirtualDom_diff(currNode, nextNode);
          				domNode = __VirtualDom_applyPatches(domNode, currNode, patches, sendToApp);
          				currNode = nextNode;

Or this block:

github.com

elm/browser/blob/1d28cd625b3ce07be6dfad51660bea6de2c905f2/src/Elm/Kernel/Browser.js#L81-L88


      
          				__VirtualDom_divertHrefToApp = divertHrefToApp;
          				var doc = view(model);
          				var nextNode = __VirtualDom_node('body')(__List_Nil)(doc.__$body);
          				var patches = __VirtualDom_diff(currNode, nextNode);
          				bodyNode = __VirtualDom_applyPatches(bodyNode, currNode, patches, sendToApp);
          				currNode = nextNode;
          				__VirtualDom_divertHrefToApp = 0;
          				(title !== doc.__$title) && (__VirtualDom_doc.title = title = doc.__$title);
