What is debugging with example?

Debugging is the process of finding and fixing errors or bugs in the source code of any software. When software does not work as expected, computer programmers study the code to determine why any errors occurred.

What are the different types of debugging?

There are two types of debugging techniques: reactive debugging and preemptive debugging. Most debugging is reactive—a defect is reported in the application or an error occurs, and the developer tries to find the root cause of the error to fix it.

How do I fix all npm issues?

Try running npm update command. It will update all the package minor versions to the latest and may fix potential security issues. If you have a vulnerability that requires manual review, you will have to raise a request to the maintainers of the dependent package to get an update.

How to clear npm cache?

Can Nodejs be hacked?

The Node. js platform is inherently secure, but because it uses third-party open source packages through its package management system (npm), it is vulnerable to cyber attacks.

What is the best way to handle errors in JavaScript?

JavaScript provides error-handling mechanism to catch runtime errors using try-catch-finally block, similar to other languages like Java or C#. try: wrap suspicious code that may throw an error in try block. catch: write code to do something in catch block when an error occurs.
