根据这里给出的答案：Convert Array to Object

var a = Immutable.fromJS({ formats: ["foo", "bar"]}); 
var b = {formats: toObject(a.get('formats').toJSON())}; 
console.log(b); 

function toObject(arr) {
  var rv = {};
  for (var i = 0; i < arr.length; ++i)
    if (arr[i] !== undefined) rv[i] = arr[i];
  return rv;
}
