1. What is node.js?

Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine. It’s an event-based, non-blocking asynchronous I/O runtime using Google’s V8 JavaScript engine and libuv library.

It means that Node.js is a program that can be used to execute JavaScript on a computer.

4 What is npm?

It’s a package manager that comes bundled with Node. It’s also the world’s largest software registry, with over 1M packages of JS code available to download.

Engaged collaboration
Learning from fellow students
Social skills
Job interview readiness
Work environment readiness

2. In your experience, which of these reasons have you found most beneficial?

Engaged collaboration and learning from fellow students

3. How does pair programming work?

Pair programming involves two roles: the Driver and Navigator. The Driver types and is the only one with keyboard access. The Driver handles the “mechanics” of the coding and manages the text editor, switching files, version control and writing the code. The Navigator uses their words to guide the Driver but does not provide direct input to the computer. The Navigator is responsible for looking at the big picture, what comes next, how an algorithm might be converted into code, and scanning for typos or bugs. The Navigator may also look up solutions and documentation.
