What are some best practices to prevent "a javascript error occurred in the main process"?

1) **Comprehensive Error Handling:** Use `try...catch` blocks and `.catch()` for Promises. 2) **Input Validation:** Validate all user input and data from external sources. 3) **Dependency Management:** Keep dependencies up-to-date and resolve conflicts. 4) **Code Reviews:** Have your code reviewed by others to catch potential errors. 5) **Testing:** Write unit and integration tests to verify the application's behavior. 6) **Robust Logging:** Implement detailed logging for debugging.
