javascript - 如何将多个对象合并为一个？

Question

当我进行http请求时，我正在获取对象数组，例如:

 [ 
  { row: '3', col: '1', val: '10:00' },
  { row: '3', col: '2', val: 'Some text' },
  { row: '3', col: '3', val: 'Yura' },
  { row: '3', col: '4', val: '676031383' },

  { row: '3', col: '6', val: '9:00 ' },
  { row: '3', col: '7', val: 'Some text' },
  { row: '3', col: '8', val: 'Alex' },
  { row: '3', col: '9', val: '965773775' },

  { row: '4', col: '1', val: '7:00' },
  { row: '4', col: '2', val: 'Some text' },
  { row: '4', col: '3', val: 'Anya' },
  { row: '4', col: '4', val: '951018689' },

  { row: '4', col: '6', val: '08:00' },
  { row: '4', col: '7', val: 'Some text' },
  { row: '4', col: '8', val: 'Dima' },
  { row: '4', col: '9', val: '961452584' },
]

问题是我需要将这些对象合并为一个，并添加一个键 - 类型，例如:

{ time: 10:00, info: 'Some text', name: 'Yura', phone: '676031383', type: 'Driver' }

{ time: 9:00, info: 'Some text', name: 'Alex', phone: '965773775', type: 'Passenger' }

{ time: 7:00, info: 'Some text', name: 'Anya', phone: '951018689', type: 'Driver' }

{ time: 8:00, info: 'Some text', name: 'Dima', phone: '951018689', type: 'Passenger' }

从1到4类型应为“Driver”，从6到9应为“Passenger” ”。响应没有 5 列，因为她是空的

有可能以某种方式做到这一点吗？我花了几个小时，但没有结果

我想，这就是你一直在追求的:

const src = [{row:'3',col:'1',val:'10:00'},{row:'3',col:'2',val:'Some text'},{row:'3',col:'3',val:'Yura'},{row:'3',col:'4',val:'676031383'},{row:'3',col:'6',val:'9:00 '},{row:'3',col:'7',val:'Some text'},{row:'3',col:'8',val:'Alex'},{row:'3',col:'9',val:'965773775'},{row:'4',col:'1',val:'7:00'},{row:'4',col:'2',val:'Some text'},{row:'4',col:'3',val:'Anya'},{row:'4',col:'4',val:'951018689'},{row:'4',col:'6',val:'08:00'},{row:'4',col:'7',val:'Some text'},{row:'4',col:'8',val:'Dima'},{row:'4',col:'9',val:'961452584'},],

      res = [...src]
        .reduceRight((r,i,_,s) => (r.push(s.splice(0,4)),r),[])
        .map((e,i) => ({time: e[0].val, info: e[1].val, name:e[2].val, phone: e[3].val, type: i&1 ? 'Passenger' : 'Driver'}))

console.log(res)

.as-console-wrapper{min-height:100%;}
