This guide aims to help beginners understand and use Vue.js 4 to build dynamic user interfaces.

What is Vue.js?

Vue.js is a progressive JavaScript framework used to build web interfaces and single-page applications. It is known for its easy-to-understand syntax and component-based architecture, making it a favorite among both novices and experienced developers.

Key Features of Vue.js 4
