> However, there was React producing some error because of my old browser, and preventing me from buying the ticket Unlikely. A general JS error could be displayed with the React logo because that's a default in certain modes. Doesn't mean React made the error. React projects are usually setup with Babel to transpile for compatibility with very old browsers. It's more likely a code error than someone setting up React without transpilation, which you have to go out of your way to do.
