数组拆分及拼接

Question

下面这样一个数组，怎么拆分拼接之后为这样
{资源/Axure Components },{资源/Sketch Templates},{资源/组件交互文档}

[{"value":"ziyuan","label":"资源","children":[{"value":"axure","label":"Axure Components"},{"value":"sketch","label":"Sketch Templates"},{"value":"jiaohu","label":"组件交互文档"}]}]

Answer 1

看了下题目是不是有写错了，{资源/Axure Components },{资源/sketch},{资源/组件交互文档}其中{资源/sketch}和其他的逻辑不一样，也没有额外说明，我理解是写错了。

不考虑扩展和其他的话，就
arr.map(e=>e.children.map(x=>`{${e.label}/${x.label}}`).join(","))[0]
arr代指目标数组。
扩展有children就需要往下算的话，就得写个方法然后递归。

试试看如下写法

const arr = [
          {
            value: "ziyuan",
            label: "资源",
            children: [
              { value: "axure", label: "Axure Components" },
              { value: "sketch", label: "Sketch Templates" },
              { value: "jiaohu", label: "组件交互文档" },
            ],
          },
        ];
        const handleArr = arr.map(item => {
            let tempArr= []
            item.children.forEach(tItem => {
                const str = `${item.label}/${tItem.label}`
                tempArr.push({str}) 
            })
            return tempArr
        })
