ReferenceError: window is not defined
Error message
ReferenceError: window is not defined
What broke
The code is trying to access the 'window' object, which is only available in browser environments. If you're running the code in a server-side context like Node.js, this object won't exist.
Why it broke
This broke because the 'window' object is part of the browser's global scope, and when executing JavaScript outside of a browser, such as on a server, it is undefined.
How to fix
To fix this, you can check if the code is running in a browser environment before accessing the 'window' object. Use a conditional statement to ensure that your code only runs in the appropriate context.
Code fix
if (typeof window !== 'undefined') { /* your code that uses window */ }Explained by ErrorOracle
