what is the difference between error and stderr in Node js

Question

I am using Node.js and want to handle errors, but I am confused when to use what can anyone of you explain?

Answer 1

Error is an object created by Node.js to handle the errors while executing your command

Stderr is a standard output stream which is used to handle errors that are ready to be executed by the Node.js but results in an error because the command itself throws the error
