I need to extend default values with options in angular way:

var defaultOptions = {
      a: 'a'
    },
    options = {
      b: 'b'
    };
var result = $.extend({}, defaultOptions, options);

Please notice, that result is a new object, because I want to preserve both of the original objects defaultOptions and options.

I'm new in Angular, could you please help me to do the same result with angular in the most elegant way?

EDIT:

I have already found angular.extend() but I can't figure out a way how to preserve defaultOptions and options.

I know that I can do it this way:

var result = angular.extend({}, defaultOptions);
angular.extend(result, options);

But it doesn't look very elegant.

You need to use angular.extend

Extends the destination object dst by copying all of the properties from the src object(s) to dst. You can specify multiple src objects.

Usage

var result = angular.extend({}, defaultOptions, options)

Angular provides an extend function.

var result = angular.extend({},defaultOptions, options)

you can use angular copy

var result = angular.copy(defaultOptions );
