Vue.js is a lightweight and flexible JavaScript framework that allows developers to easily build dynamic and reactive user interfaces. Its intuitive syntax, modular architecture, and focus on performance make it a popular choice for modern web development.

A UI kit provides developers with a set of reusable components that can be easily integrated into a website or application. These components are pre-designed with consistent styling and functionality, allowing developers to save time and effort in the design and development process. UI kits can be either custom-built or third-party, and often include components for buttons, forms, typography, icons, and more.

RollupJS is a popular and efficient JavaScript module bundler that takes the code from multiple modules and packages them into a single optimized file, minimizing the overall size of the application and improving its performance.
