有点拗口啊

Topic source

#1 Created at ... [Delete] [Delete and Lock User]

个有效的变量，就需要用''括起来。访问这个属性也无法使用.操作符，必须用['xxx']来访问：

这个难道就没有一个对应的名词可以解释麽？

#2 Created at ... [Delete] [Delete and Lock User]

或者说，对象属性设置成字符串 有什么作用？

#3 Created at ... [Delete] [Delete and Lock User]

好吧，确实是太自由，‘’引号只是为了给那些不遵守规则的人使用的
