We target IE11 with angular1.6, React and Vue and it all runs very fast. The only time we ever had trouble were lists over a few hundred items long that our internal customers didn’t want paginated. But delivering those more demanding apps in react and vue solves all our IE11 is slow problems. On any other brothers the code might as well be native.
We have one small piece written in React. It will be replaced when the Angular is finished being moved to Vue, and all new dev is in Vue. It’s a nearly 8 year old bundle of over 56 and counting HR apps and is a feather in our department’s cap for how much money it has saved.
I wanted to move to React initially but after adding a single new app my boss hated the syntax and we switched to Vue. Vue is good too.
Lol yes it definitely does. But we still get to use all the syntactic sugar of es latest and IE11 stays very fast. We’re happy and so are our customers.
And they never kept track of their dependencies in the first place. That's the job of some build tool. Whatever it pulls in is fine.
