The use of namespaces can help identify what function or utility the code provides, or even help specify its origin.

使用名称空间可以帮助识别代码提供的函数或实用程序，甚至可以帮助指定其来源。

When you use it in your own component code, users will be able to execute code regardless of origin (such as from an Internet site), and their systems will remain safe.

当您在您自己的组件代码中使用它时，用户可以在不用留心来源的情况下执行代码（比如从一个英特网网站），他们的系统仍旧是安全的。

For instance, until a few years ago the origin of the genetic code and of protein synthesis were considered synonymous with the appearance of life itself.

比如说，直到最近，生命起源的遗传密码和蛋白质合成在生命产生之初的同步问题仍然在困扰着我们。
