Simply map the original array to an array of objects.

var arr = [
  238,
  259,
  276,
  307
];

var dataset = arr.map(function(value, index) {
  return {
    key: index,
    value: value
  };
});

document.body.innerHTML = '<pre>' + JSON.stringify(dataset, null, 2) + '</pre>';

try this one

var array = [

  259,
  276,
  307
];

var dataset ={};
 array.map(function(value, index) {  
    dataset[index]= value
});
