：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; 
}
