What are common Babel error messages and how can I fix them?

I'm getting a 'Babel is not defined' error. What does that mean?

The 'Babel is not defined' error usually means that Babel isn't properly installed or configured in your project.

How can I fix that? I thought I installed it.

Make sure you have Babel installed in your project. You can check your package.json or run 'npm install --save-dev @babel/core'.

I did that, but now I'm seeing a 'Babel loader not found' error.

This error indicates that the Babel loader for Webpack is missing. You can install it using 'npm install --save-dev babel-loader'.

Thanks! What about the 'Unexpected token' error?

The 'Unexpected token' error often occurs when Babel isn't set up to transpile your code correctly. Check your .babelrc configuration.
