How should I detect incompatible browsers?

I’ve created a large single page app using vue.js. Now I would like to detect browsers which are incompatible with vue.js and display a helpful error message to the user. I could grab one of many existing browser detection tools and make good guesses about which browsers should work but I would rather use feature detection as that is the recommend way to go.

Do you have any recommendations on how to detect which browsers should be able to run vue.js? Would it be sufficient to just check for Object.prototype.__defineSetter__?

Personally, after much testing, for Vue the minimum you need is the following:

var compatibleBrowser = typeof Object['__defineSetter__'] === 'function';

@pixelbacon this will return ‘false’ for ie10 where vue is working fine.
