TCS Vue JS Interview Questions and Answers

If you are preparing for a TCS interview for a position requiring 1 to 4 years of experience in Vue.js, then you might want to review these common interview questions and their answers.

1. What is Vue.js and what are its key features?

Vue.js is a progressive JavaScript framework used for building user interfaces. Its key features include reactivity, components, virtual DOM, and easy integration with other libraries or existing projects.

2. Explain the Vue instance lifecycle.

The Vue instance lifecycle consists of several stages, including creation, mounting, updating, and destruction. Each stage has corresponding hooks such as created, mounted, updated, and destroyed, which allow developers to perform actions at different points in the lifecycle.

3. What is a component in Vue.js and how do you create one?

A component in Vue.js is a reusable and modular UI element. It encapsulates data, template, and behavior into a single unit. To create a component, you can use the Vue.component() method, define a template, and specify the data and methods associated with the component.

4. What is Vuex and when would you use it?

Vuex is a state management pattern and library for Vue.js applications. It enables centralized state management, making it easier to manage data across components. Vuex is typically used in larger applications with complex data flows or when multiple components need access to the same data.

These are just a few examples of the types of questions you might encounter in a TCS Vue.js interview. It’s important to review the Vue.js documentation, practice coding exercises, and be prepared to discuss your past experience with Vue.js projects.
