Array of Array to an Object

Question

I have an array like

var myArray = [
  [ '12345678912312', '982322' ],
  [ '98789213123123', '443434' ],
  [ '34534565465645', '387423' ],
  [ '67898798799299', '345334' ],
  [ '09324242342342', '234232' ],
];

which I want to convert into an Array of object, something like:

var myObject = [
  {
    id: '12345678912312',
    num: '982322',
    hour: new Date.getHours(),
  },
  {
    id: '98789213123123',
    num: '443434',
    hour: new Date.getHours(),
  },
  {
    id: '34534565465645',
    num: '387423',
    hour: new Date.getHours(),
  },
  {
    id: '67898798799299',
    num: '345334',
    hour: new Date.getHours(),
  },
  {
    id: '09324242342342',
    num: '234232',
    hour: new Date.getHours(),
  },
];

I am using Underscore currently and wondering how (and if) I can use _.object and/or _.map to achieve something like this.

I will also like it to be return-able thing. Like:

var newVar = _.object(_.map(myArray), function(k, v) {
  // Do something
});

Thank you!

You just need to map. return {id:x[0],num:x[1],hour:new Date.getHours()}. What you got is a collection. — elclanrs

I don't think _.object needs a predicate. as you are trying to give. — Mritunjay

If I understood what you want, This can be done with simple javascript native map

var myObj = myArray.map(function(el){
            return {id:el[0],num:el[1],hour:new Date().getHours()}
            });
