How to make object which store unique key have multiple different values-CodePudding

    var data = [{type: 'physical', value: 'verified'}, 
                {type: 'reference', value: 'owner'},
                {type: 'physical', value: 'pending'},
                {type: 'document', value: 'pending'}
               ]

How to return object in such a way which should have unique key which store mulpltiple values

Expected Result =

  var data  = {
      physical: ['verified', 'pending'],
      reference: ['owner'],
      document: ['pending']
  }

CodePudding user response：

You can reduce the data array to an object and build the properties as well as the values in each property using spread operator, destructuring, and nullish coalescing.

data.reduce((acc, { type, value }) => ({
    ...acc,
    [type]: [...(acc[type] ?? []), value]
}), {});

CodePudding user response：

this function should return the result as you asked.

function getUnique(data){
    let x = {};
    for(let i of data){
        if (!x[i.type]){x[i.type] = [];}
        x[i.type].push(i.value);
    }
    return x;
}
