Answer 1

No, Express knowledge is not required for learning javascript.

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. which is written in javascript. In order to use express you should have basic knowledge of javascript and ES5 features for Node.js.

Check your package.json for information whether you have installed express as dependency or not.
