What is the equivalent of jQuery $.extend() in Ember.js?

Question

I used to clone a variable in jquery like this:

var clone = $.extend(true, {}, orig);

Is there any method in Ember.js that is equivalent to this?

Answer 1

That's like my least favorite named method in jquery. Every time I want to merge two objects it takes me a few seconds of trying to think of what it's called. You can also use assign in Ember.

Ember.assign({first: 'Tom'}, {last: 'Dale'}); // {first: 'Tom', last: 'Dale'}
var a = {first: 'Yehuda'}, b = {last: 'Katz'};
Ember.assign(a, b); // a == {first: 'Yehuda', last: 'Katz'}, b == {last: 'Katz'}

or in your case

Ember.assign({}, orig);

But, you should note, it doesn't support deep cloning like copy does.

Answer 2

Yes there is: Ember.copy

var clonedObj = Ember.copy(originalObj, true);
