简介： 前端代码分享——星空背景特效（内含源码）


运行演示



打开网页效果最好哦

提供的JavaScript代码是一个名为"WarpDrive"的jQuery插件，它创建了一个星空动画，类似于科幻媒体（如《星际迷航》）中所看到的"超光速"效果。

前端全栈之路Deno篇（二）：几行代码打包后接近100M？别慌，带你掌握Deno2.0的安装到项目构建全流程、剖析构建物并了解其好处
在使用 Deno 构建项目时，生成的可执行文件体积较大，通常接近 100 MB，而 Node.js 构建的项目体积则要小得多。这是由于 Deno 包含了完整的 V8 引擎和运行时，使其能够在目标设备上独立运行，无需额外安装依赖。尽管体积较大，但 Deno 提供了更好的安全性和部署便利性。通过裁剪功能、使用压缩工具等方法，可以优化可执行文件的体积。

揭秘前端高手的秘密武器：深度解析递归组件与动态组件的奥妙，让你代码效率翻倍！
【10月更文挑战第23天】在Web开发中，组件化已成为主流。本文深入探讨了递归组件与动态组件的概念、应用及实现方式。递归组件通过在组件内部调用自身，适用于处理层级结构数据，如菜单和树形控件。动态组件则根据数据变化动态切换组件显示，适用于不同业务逻辑下的组件展示。通过示例，展示了这两种组件的实现方法及其在实际开发中的应用价值。
