Ember.assign()

Copy properties from a source object to a target object.

var a = { first: 'Yehuda' };
var b = { last: 'Katz' };
var c = { company: 'Tilde Inc.' };
Ember.assign(a, b, c); // a === { first: 'Yehuda', last: 'Katz', company: 'Tilde Inc.' }, b === { last: 'Katz' }, c === { company: 'Tilde Inc.' }
