ngrx is a powerful state management library for Angular applications. It is based on the principles of Redux and provides a predictable state container for managing the application’s state. As ngrx becomes increasingly popular, it is important for developers to be well-prepared for interviews that focus on this library. In this article, we will explore some common ngrx interview questions and provide answers to help you ace your next interview.
Before we dive into the interview questions, let’s briefly review what ngrx is and why it is used. ngrx is a framework-agnostic implementation of Redux for Angular applications. It helps manage the state of an application in a predictable manner, making it easier to develop, test, and maintain. ngrx follows a unidirectional data flow pattern, where actions trigger state changes through reducers, and the updated state is then propagated to the components.
Now that we have a basic understanding of ngrx, let’s explore some commonly asked interview questions related to it.
