Here's a potentially dumb question about React: can it be used inside a client-side application that was written using Angular?<p>Part of my job involves customizing a commercial, closed-source web application that lets you build web forms. The application's front-end was written using Angular, but it lets you add your own custom JavaScript to add more functionality to forms, such as character counts, hiding/showing relevant fields based on conditions and auto-capitalization of user input. Basically, each form has its own JSFiddle-like section that gets published alongside the form.<p>We currently use native JS and JQuery for these customizations, usually within a monolithic document.ready block. The problem is that our code can get pretty complex, especially when hooking up multiple event handlers to the same elements. I've been thinking that React may be able to solve this problem, but I'm uncertain about using it alongside Angular, especially since I have no control over the latter.<p>Based on this description, would there be any advantages to trying to shoehorn React into our projects, or should we stick with native JS and JQuery?
