How to assign a variable in to an object of an array?

Question

I have an array like this,

var items = ['1','2','3']

and i want the output as newItems = [{'id':1}.{'id':2},{'id':3}];

  newItems = [{'id':''}]
  for(var i = 0;i<items.length;i++){
           newItems[i].id = type[i];
  }

Can anyone please help me.Thanks.

You can use map method for this, which creates a new array and applies a provided callback function for every item in the array.

var items = ['1','2','3']
console.log(items.map(function(item){
  return {"id":item}
}));

Use map:

newItems = items.map(function(item) { return {'id': parseInt(item) }; });

EDIT: I added parseInt() since the user's desired output included unquoted integers.

var items = ['1','2','3'];
var newItems = items.map(function(item) {
  var obj = {};
  obj.id = +item; // '+' if you wish to convert item from string to number
  return obj;
});

console.log(newItems); //[{'id':1},{'id':2},{'id':3}]
