I'm trying to figure out why my react code won't run. I just set up a router for linking in the Nav but now my render function won't render on any of the pages and I don't know why. Please check out the link to my Code Sandbox for reference code Sand box I would like my file to at least be running. I am using Bootstrap I don't think that is the issue though.
Error:(386, 23) TS2583: Cannot find name 'Set'. Do you need to change your target library? Try changing the `lib` compiler option to es2015 or later.
