I found myself slipping in the architect role on a few recent projects with various employers and being forced to make the call on which front end framework to use. The problem is that there are so many to choose from and it very hard to predict what you will need in terms of features from your chosen framework six months or longer after making your decision.
Plus, your fellow devs will probably be arguing with you over which one is better based on their experience. All the emails and messages pointing me to various websites claiming React/Vue/Angular etc is best with stats and graphs I really don't have to the time to get my head around.
It's that fear of making the wrong choice that bothers me. The idea a year down the line the front end seems a bit sluggish and someone then points out that {other_framework} would be flying with the same workload.
Don't get me wrong choice is good, but with so much going on in the world of front-end right now coupled with all the hype and shouts about which is best it is hard to just pick one and run with it. Especially in the metric driven world we live in where a manager who doesn't get tech will berate you for choosing the wrong framework or wonder why you aren't buying in the latest hyped up framework.
That being said my preference is to use a framework to prototype and then convert to plain old JS where possible.
