Basic Vue JS Interview Questions
The following set of Vue.js interview questions should test the candidate’s basic
knowledge of Vue and some of its core features.
1. What are components in Vue?
All front-end frameworks have a different component system to handle the UI layer. The
interviewer might ask this question to gain an understanding of the candidate’s knowledge
of components in general and how they play an important role when building front-end
applications. The candidate should also be able to explain at a high level the role and
advantages of components within the Vue framework.
Components are the basic building blocks of the user interface of every application.
Components allow us to split the UI into smaller, independent, and reusable pieces.
The concept of components isn’t Vue specific, however, Vue has its own component
model that provides encapsulation of the content and logic within each component.
2. How do you create components in Vue?
This beginner’s Vue interview question is likely to be a follow-up to the previous question
regarding components in Vue. The candidate should be able to explain the two approaches
to create a component in Vue along with their differences and applications
There are two ways to create a component in Vue. Depending on whether we have a
build step or not, we can either use a single-file component or a JavaScript object. When
using a build step, we typically use a single-file component. The Vue component is placed in
a single dedicated file using the `.vue` extension.
Without a build step, the Vue component can be defined as a plain JavaScript object
