Are there differences in error handling between the main process and renderer processes in Electron?

Yes, there are significant differences. The main process runs Node.js and has access to the operating system and its modules. Errors here can crash the entire application. Renderer processes run in a browser environment, and their errors typically only affect that specific window. Renderer process errors can be caught using `try...catch` within the renderer's JavaScript or by attaching an error handler to the `window` object (`window.onerror`). The main process has access to Node.js specific error handling mechanisms like `process.on('uncaughtException')`.
