javascript - 在 map 函数javascript上连接字符串

我有一个对象lengthOfStay，我试图在其中连接值并将其放在customerApplication.lengthOfStay上

lengthOfStay:{
    yrs: '',
    mos:''
},
customerApplication: {
    length_of_stay: this.lengthOfStayYrsMos
}

computed: {
     lengthOfStayYrsMos(){
        return this.customerApplication.length_of_stay =
        Object.keys(this.lengthOfStay).map(k =>  this.lengthOfStay[k]).join(" ")
      }
}

因此对于串联来说看起来不错，例如，结果是

lengthOfStay:{
    yrs: '2',
    mos:'2'
},
//result
customerApplication: {
    length_of_stay: "2 2"
}

如何在其上连接字符串？这样的结果是

customerApplication: {
    length_of_stay: "2 Yrs. & 2 Mos."
}

最佳答案

尝试这个：

Object.keys(this.lengthOfStay).map(k =>  {
   return `${this.lengthOfStay[k]} ${k}.`
}).join(" & ")

第一次大写

Object.keys(this.lengthOfStay).map(k =>  {
   return `${this.lengthOfStay[k]} ${k.charAt(0).toUpperCase() + k.slice(1)}.`
}).join(" & ")
