Implement Efficient Virtual Scrolling with Vue.js

Introduction

In this project, you will learn how to implement a virtual scrolling list using Vue.js. Virtual scrolling is a technique that only renders the visible area of a large dataset, rather than rendering or partially rendering the data in the non-visible area. This achieves extremely high rendering performance and is suitable for rendering a large number of data with a small volume.
