+Production and development builds of React slightly differ in the way `componentDidCatch()` handles errors.
+
+On development, the errors will bubble up to `window`, this means that any `window.onerror` or `window.addEventListener('error', callback)` will intercept the errors that have been caught by `componentDidCatch()`.
+
+On production, instead, the errors will not bubble up, which means any ancestor error handler will only receive errors not explictly caught by `componentDidCatch()`.

 > In the event of an error, you can render a fallback UI with `componentDidCatch()` by calling `setState`, but this will be deprecated in a future release.
