Numeric-key objects result in sparse arrays

[dharkness]

Reading through some of the other issues, it seems this may be intended behavior. We have enabled the option to output brackets around array indices.

{
  items: [
    {
      123: 'foo',
      456: 'bar'
    }
  ]
}

// dot.dot(obj)

{
  'items[0].123': 'foo',
  'items[0].456': 'bar'
}

But when you run that through dot.object(), you don't get the original object. You get a sparse array instead.

{
  items: [
    [
      ...123 empty slots...
      'foo',
      ...333 empty slots...
      'bar'
    ]
  ]
}

Is there an option to use objects for . in all cases, even when the key is an integer?

Running into this issue as well. Would love some resolution.

@dharkness unsure if you're still dealing with this problem, but I seem to have found a workaround. Fortunately or unfortunately, you will need to modify your code a bit to init a Dot class, with the useArray flag set to false:

const util = new dot('.', false, false, true);

Once that's done, you can run the object method on your object and you should get the results you're expecting:

let dot = require('dot-object');
let util = new dot('.', false, false, true);
let data = {
  items: [
    {
      123: 'foo',
      456: 'bar'
    }
  ]
};

let results = util.object(data);

where results is { items: [ { '123': 'foo', '456': 'bar' } ] }
