Answer 1

It looks like ReactJS can only work with the IE 9, IE 10 and IE 11 versions. To support the IE 9, IE 10 and IE 11 you need to add polyfills. IE versions older then IE 9 are not supported.

So it looks like you cannot run the ReactJS app on the IE 7 or IE 8 browser. The IE 7 and IE 8 are too old versions and out of support scope of the Microsoft. I suggest you to use the latest Microsoft browser to avoid such kind of issues. If you are not able to move to the latest Microsoft browser then at least try to use the IE 11 browser.
