I have some ES2015 classes and need to produce object by one of them in my function. I get class name as string. How can I do this? Now I am using switch … case, but it look monstrous, you know.

let classname = 'MyClass';
new window[classname](); // TypeError: window.MyClass is not a constructor

Is it here a more nice way?

Is there an object which `MyClass` is a property of? If not, you could make one and use that instead of switch/case. – Alexander O'Mara Apr 25 '16 at 00:18
`classes` (even global ones) are not part of the global object. – Bergi Apr 25 '16 at 00:23
