Error Handling
Error handling is used to ensure the smooth running of your software or program in case of any undetected issue in your software. But in Node JS, there is no way to handle errors automatically through any module. Developers can setup error handling using try catch blocks or event emitters. But in Express JS, it is much easier to handle errors because there are multiple ways to handle errors, like asynchronous handling, global error handling, etc.
Syntax:
throw new Error('Error');
