Errors occur when something went wrong, during the Program execution. There are different types of errors and these should be handled properly in the program to avoid abnormal program termination.
Node.js provides different ways to handle the errors generated while running the Applications in Node.js run-time environment. We can handle the errors using
EventEmitter class object emits the error events when an error occurs and the attached listeners should handle the events. Otherwise, an error is thrown and the Application exits.
Error object captures the stack trace information and it is more useful to resolve the errors.
