using DataCollection with functional libraries

Webix JS
1

Have noticed that some underscore / lodash methods can’t applied to DataCollection because it doesn’t have a ‘length’ property.

Would it be possible to implement this so that on could, for example, do:

var selected_items = _.filter($$('datatable_one').data, function (o) {  
     o.checked == true
})

Unfortunately .data is not an array of the data - it is instance of DataStore

yep, but it sure would be nice to be able to filter, map, and reduce, over the datastore
