我运行JSlint并看到了这样的错误：
'foo' is not defined. var x = foo();
foois a function defined in another JavaScriptfile foo.js. As I understand there is no "import / require" directives in JavaScriptto reference the foofunction defined in another source file.
foo是另一个JavaScript文件中定义的函数foo.js。据我了解，没有“导入/要求”指令JavaScript来引用foo另一个源文件中定义的函数。

Use the global directive to tell JSLint about foo's assumed existence.
使用 global 指令告诉 JSLint 关于foo的假定存在。
/*global foo */
