Test details ## Know what to expect. Review the instructions, covered skills, example question themes, and intended audience before beginning. 01 ### Instructions and covered skills Read each question carefully before selecting your answer. No external resources or collaboration allowed. Stay focused and manage your time wisely. Ensure you understand Vue.js component and prop syntax, including shorthand and conventions. Turn off notifications to avoid distractions. ### Key Areas * Component declaration and registration (local vs global) * Prop definition: types, required, default, validator functions * Dynamic prop binding with v-bind * One-way data flow and mutation prevention * Using props in templates and JavaScript * Prop naming conventions (camelCase in JS, kebab-case in templates) * The .sync modifier for two-way binding (Vue 2) or v-model on components * Fallthrough attributes and props inheritance ### Recommended Preparation Review Vue.js official documentation on Components Basics and Props. Practice creating reusable components with varying prop configurations. Understand how to use v-bind to pass data dynamically, including object spread syntax. Familiarize yourself with prop validation and custom validators. Study examples of component composition and prop-driven templating. 02 ### Examples of questions What is the correct way to define a prop in a Vue component? How do you pass a dynamic value as a prop to a child component? Which of the following prop types is NOT supported by Vue's prop validation? When using camelCase prop names in JavaScript, what convention should you use in templates? What happens if a required prop is not passed to a component? How can you set a default value for a prop? What is the purpose of the .sync modifier on a prop? Which lifecycle hook is best for accessing props passed to a component? How do you pass all properties of an object as props to a child component? What is the primary direction of data flow for props in Vue? 03 ### Who this test is best for Intermediate Vue.js developers who have experience building component-based UIs and need to validate their knowledge of proper prop usage and component patterns.
