Does Node.js and Angula.js differs from Javascript?

Question

Taking the course on Javascript, I noticed that the Node.Js was embedded in the course while that of Angula.js is a separate course. What is the major difference and similarities among them?

Answer 1

In term of functionalities, these 2 javascript frameworks have totally different of purpose. They cannot replace each other, they only can work together to form better web access.

Nodejs runs from backend server to parse and response html pages or api data, and interacting with databases.

Whereas Angular.js is runs from visitor's frontend browsers to further manipulate html pages and data that responded from server.
