这个版本库也会随着本书的修订而更新。当版本库更新时，我会打上版本标签，这样当你
在读本书的某个版本时，便可以检出对应版本的代码。版本库当前的版本是
2.0.0
。我会大
致遵循
语义版本
的原则（本章后面会做更多说明）。补丁增量（最后一个数字）表示微小
变更，不太会影响你跟随该版本的书本学习。也就是说，如果版本库处于版本
2.0.15
，则
依旧对应本书的当前版。可是，如果小版本增量（第二个数字）不同（
2.1.0
）
，则说明版
本库的内容跟当前你在读的这个版本有所不同了，你应该检出版本标签以
2.0
开头的版本。
版本库从优使用
README.md
文件对示例代码进行说明。
无论何时你想要做些试验，要记得，是从标签检出的版本使你进入了
Git
所
说的“分离头”状态。尽管你可以放心地编辑任何文件，但如果不先创建一
个分支，你提交东西就不安全。因此，如果的确想要一个基于某个标签的试
验性分支，只需创建一个新的分支并检出。对此，使用一条命令即可：
git
checkout -b experiment
（这里
experiment
就是你的分支名，想叫什么都可
以）。然后在这个分支上，所有编辑和提交都是安全的。

npm
包
项目依赖的
npm
包就位于名为
node_modules
的目录下（称其为
node_modules
而不是
npm_packages
有些遗憾
，因为
Node
模块虽然相关却是不同的概念）。你可以放心地探索这
个目录，不管是为了满足好奇心还是为了调试程序，但千万不要修改里面的任何代码。随
意修改代码本就是个坏习惯，而且你所做的所有修改都可能被 ...
