This problem appears like –
ERROR in src\index.js
Line : ‘root’ is not defined no-undef
This means , you have used ‘root’ in your code but you haven’t defined it yet, so basically the root can be defined as –
const root = ReactDOM.createRoot(document.getElementById('root'));
Just include above lines in code , surely your problem will be solved , if not , then let me know , We will try to solve it.
Thankyou! for reading.
