After going through a ‘meteor with react’ tutorial, which explained the use of mixins (and after understanding how it works clearly!), I later found the below noted writeup at https://facebook.github.io/react/docs/reusable-components.html
“Unfortunately ES6 launched without any mixin support. Therefore, there is no support for mixins when you use React with ES6 classes. Instead, we’re working on making it easier to support such use cases without resorting to mixins.”
So, what is the best alternative to choose now?
