Convert javascript array to object of same keys/values

rated 0 times [ 82] [ 1] / answers: 1 / hits: 36933 / 8 Years ago, sat, july 23, 2016, 12:00:00

I have a function that returns an array, as follows:

But I'm trying to populate a SweetAlert2 dialog.

As the documentation exemplifies, the desired input would look like this

inputOptions: {

    'SRB': 'Serbia',

    'UKR': 'Ukraine',

    'HRV': 'Croatia'

  },

How could I convert my array to the needed format, considering that the key will be the same as the value?

So, something like this would be the result:

{

    'aaa123': 'aaa123',

    'Açucena': 'Açucena',

    'Braúnas': 'Braúnas',

    [...]

}

I have tried JSON.stringify, but the output is not what I need:

[[aaa123,Açucena,Braúnas,C.
Fabriciano,gege,gegeq2,Ipatinga,Joanésia,Mesquita,Rodoviário,teste,teste2,Timóteo,Tomatoentro,ts]]

This can be done with a simple reduce call:

// Demo data

var source = ['someValue1', 'someValue2', 'someValue3', 'other4', 'other5'];





// This is the conversion part

var obj = source.reduce(function(o, val) { o[val] = val; return o; }, {});





// Demo output

document.write(JSON.stringify(obj));
