How to merge objects and append it into new array if object values are same using JavaScript?-CodePudding

I have this kind of data, my goal is to find all same request_id values in the given objects, merge it to one object and append its unique_id into one array, How can I get this result?

let fakeData = {
    "622b1e4a8c73d4742a66434e212":{
      request_id: "1",
      uique_id:'001'
    },
    "622b1e4a8c73d4742a6643423e54":{
        request_id: "1",
        uique_id:'002'
    },
    "622b1e4a8c73d4742a6643423e23":{
        request_id: "2",
        uique_id:'003'
    },
  }

  let parts = []

  for (const property in fakeData) {
      console.log(fakeData[property]);
  }


  //Result should be
  // [{request_id:'1', values:["001, 002"]}, {request_id:'2', values:["003"]}]

CodePudding user response：

You can iterate over all the values using Object.values() and array#reduce. In the array#reduce group based on request_id in an object and extract all the values of these object using Object.values().

const fakeData = { "622b1e4a8c73d4742a66434e212": { request_id: "1", uique_id: '001' }, "622b1e4a8c73d4742a6643423e54": { request_id: "1", uique_id: '002' }, "622b1e4a8c73d4742a6643423e23": { request_id: "2", uique_id: '003' }, },
      output = Object.values(fakeData).reduce((r, {request_id, uique_id}) => {
        r[request_id] ??= {request_id, values: []};
        r[request_id].values.push(uique_id);
        return r;
      },{}),
      result = Object.values(output);
console.log(result);
