NPM (Node Package Manager) is a package manager for Node.js. It allows developers to install and manage dependencies for their Node.js projects. A Node.js developer should know how to use NPM to install and manage packages.
What is the difference between callback and promise in Node.js?
Callbacks and Promises are two different ways of handling asynchronous operations in Node.js. A Node.js developer should know the difference between these two and when to use them.
What is Git, and how do you use it with Github?
Git is a distributed version control system that allows developers to track changes in their codebase over time. Github is a web-based hosting service that provides Git repository hosting and other collaboration features. A Node.js developer should know how to use Git and Github to collaborate with other developers and manage code versions.
What are the advantages of using Node.js?
Node.js offers several advantages for developers, such as fast performance, scalability, and a large community of developers and packages.
