Convert Array into Object + setting propertie names

I've got an Object with variable propertie names and im converting it into an array: 

var test = Object.getOwnPropertyNames(obj); //[a, b, c]

Now I've got my array of Property names. The next step I want to take is to turn this array into an Array of objects like this: 

newObj= [ { "name": a }, {"name": b} , {"name" : c }]

How can I achieve that?

Simple approach without getOwnPropertyNames function(using Object.keys function):

// obj is your initial object
var newArr = Object.keys(obj).map(function(k) { return { name: k }; });

Try this (using Object.getOwnPropertyNames itself)

var obj =  { a :1, b:2, c:3 };
var output = Object.getOwnPropertyNames(obj).map( function( key ){  
  return { "name" : obj[ key ] } ;
});

console.log(output);

You can utilize Array.prototype.map - it transforms sequence into a new array by applying a function to each item, which is wrapping to an object with name property in your case:

var names = ["a", "b", "c"];
var newObj = names.map(function(n) { return { name: n }; });

console.log(newObj);

Combining with your getOwnPropertyNames usage, it can look like:

var newObj = Object.getOwnPropertyNames(obj).map(function(n) { return { name: n }; });
