Trying to solve the javascript calculator for the certification and nobody can get these tests to pass…

I found the answer in a post by jeremy.a.gray

I had to change the external scripts in codepen to use react17 instead of 18.

This is can be done by changing
https://unpkg.com/react/umd/react.production.min.js
https://unpkg.com/react-dom/umd/react-dom.production.min.js

to

https://unpkg.com/react@17/umd/react.production.min.js
https://unpkg.com/react-dom@17/umd/react-dom.production.min.js

And then changed the code from

const root = ReactDOM.render(document.getElementById("root")); root.render(<Calculator />);

to

ReactDOM.render(<Calculator />, document.getElementById("root"))
