Angular object array to column array

Question

I have object, which has field id and text and possibly more other fields.

There are lots of objects in the array, and I want to convert it to a text array.

This is what I have at the moment. Any prettier solution, possible something LINQ like?

var emails = new Array();
angular.forEach(this.form.Emails, function (email) {
    emails.push(email.text);
});

You could use something like underscore and use their map() functions. Another interesting choice can be seen here: stackoverflow.com/questions/15411620/… — Nix

Like @Nix answered you, you can use pluck of Underscore library.

extracting a list of property values

Example:

this.form.Emails = [
                    {text: 'moe', id: 1},
                    {text: 'larry', id: 2},
                    {text: 'curly', id: 3}
                   ];

var emails = _.pluck(this.form.Emails, 'text');

//ouput
 ["moe", "larry", "curly"]

Anyways I suggest you to leave your code version as is (aka angular.forEach). Because other programmer that maintains your code must know what pluck does.
