How to map array of object dynamically

var data = [

    { extn: '2014', agentid: 'sravya', comments: '' },

    { extn: '2015', agentid: 'shalini', comments: '' }

    ]

 const localityParameterSets = data.map(function(value){

       return [

            {name:"extn",value:{stringValue:value['extn']}},

            {name:"agentid",value:{stringValue:value['agentid']}},

            {name:"comments",value:{stringValue:value['comments']}}

            ]

    })

    console.log(JSON.stringify(localityParameterSets))

The above code is working fine but I need to make this name and value dynamically without hardcode i.e key value
for example "extn" string is hardcoded instead key value should come
"agentid" string is hardcoded instead key value should come

>Solution :

Use Object.entries and build the object dynamically.

var data = [

  {
    extn: '2014',
    agentid: 'sravya',
    comments: ''
  },

  {
    extn: '2015',
    agentid: 'shalini',
    comments: ''
  }

]

const localityParameterSets = data.map(function(value) {

  return Object.entries(value).map( ([key,val]) => ({name:key, value:{stringValue:val}})) 
  
})

console.log(localityParameterSets)
