A modern build pipeline typically consists of:

- A package manager, such as Yarn or npm. It lets you take advantage of a vast ecosystem of third-party packages, and easily install or update them.
- 包管理器，如Yarn或npm。它允许您更多的使用第三方包的生态系统，并轻松地安装或更新它们。
- A bundler, such as webpack or Browserify. It lets you write modular code and bundle it together into small packages to optimize load time.
- 打包工具，例如webpack或Browserify。它允许您编写模块化代码，并将它们捆绑在一起成为小包以优化加载时间。
- A compiler such as Babel. It lets you write modern JavaScript code that still works in older browsers.
