"esversion": 6
时，箭头功能警告消失，但我收到 async 和 wait 警告。当我将 esversion 设置为 8 或 9 时，异步和等待警告消失，但箭头函数警告重新出现。我认为 ES9 支持箭头函数。有没有办法让 JSHint 允许两者？

// == Enforcing Options ===============================================
//
// These options tell JSHint to be more strict towards your code. Use
// them if you want to allow only a safe subset of JavaScript, very
// useful when your codebase is shared with a big number of developers
// with different skill levels. Was all true.

// == Environments ====================================================
//
// These options pre-define global variables that are exposed by

"prototypejs" : false, // Enable globals exposed by Prototype JavaScript framework.
"rhino" : false, // Enable globals available when your code is running inside of the Rhino runtime environment.

"yui" : false, //?since version? This option defines globals exposed by the YUI JavaScript framework.
// == JSLint Legacy ===================================================

// not be improved in any way and might be removed at any point.
"nomen" : false, // Prohibit use of initial or trailing underbars in names.

"predef" : [ // Extra globals.
//"exampleVar",
//"anotherCoolGlobal",
//"iLoveDouglas"
"Java", "JavaFX", "$ARG" //no effect

}
编辑，我确实通过向全局添加 async 和 wait 找到了解决方案，但我认为有比这更好的解决方案。
"globals" : {
"async" : true,
"await" : true,
"describe" : true,
"expect" : true,
"it" : true
},
感谢所有花时间思考这个问题的人。
