我有以下对象React：

const userData = 
  {
    id: 30,
    firstName: "James",
    lastName: "Anderson",
    programmingLanguage: "Java, Python",              # HERE
    LanguageSpoken: "French, German, English",        # HERE
    Nationality: "French",
    Hobby: "Developer, Hiking"                        # HERE
  },
]

什么是循环的最佳方式，通过这个对象，改造3个字段programmingLanguage ，LanguageSpoken 并且Hobby ，其类型string为字符串列表（类型）。

所以改造后应该是这个样子。

const userData = 
  {
    id: 30,
    firstName: "James",
    lastName: "Anderson",
    programmingLanguage: ["Java", "Python"],         # List of strings
    LanguageSpoken: ["French", "German", "English"], # List of strings
    Nationality: "French",
    Hobby: ["Developer", "Hiking"]                   # List of strings         
  }, …
