猫鼬模式：ropertyname以数字开头

Question

是否可以用数字开头我的猫鼬属性的名称？ 定义猫鼬模式时，我将此标记为错误：

...
name: {type: String, required: true},
50WeekAverage: {type:Number, required: true},
50DayAverage: {type:Number, required: true}
...

以下标记未标记为错误，但是如果我现在编写的属性名带有或不带有仲裁数，我是否会遇到麻烦？

...
 name: {type: String, required: true},
"50WeekAverage": {type:Number, required: true},
"50DayAverage": {type:Number, required: true}
...
