IE 10 support

[bvaughn]

The error you reference is only thrown if the Component you polyfill doesn't have an isReactComponent property on its prototype. This property is set by React on Component (and PureComponent), and your component should inherit it so long as it extends one of those two classes.

Since you mention IE 10 specifically, it does not support JavaScript class syntax. This means that you'll need to use something like Babel to compile your code before running it.

If you are doing this and still seeing the error, we'll need more information bout how to reproduce the problem. (For example, you can provide a Code Sandbox that shows all of your code, or an example GitHub repo that could be checked out and run locally.

PS. Can you load this URL in IE 10 by chance?

https://build-bmxsryfowt.now.sh isn't loading in ie 10, because you haven't polyfilled Set and Map.

I'm familiar with that requirement. 😄 The app I deployed to build-bmxsryfowt.now.sh used the polyfills mentioned on ReactJS.org specifically. I messed up though by putting them in App.js rather than index.js (after React has been initialized in other words). Try again:

It works 😄
Must be something we done in our project. I'll investigate more.

When you figure out the cause– let me know, if you think about it. It might be helpful in the future for someone else. 😄
