Question

I have a function that uses an array to set names for different things

var settings = {
    slug: "foo"
}

Now, i want to create a variable, whitch name is the value of settings.slug, in this case foo

This obviously does not work:

var settings.slug = new Schema({
  title : String
, content   : String
});

The only way to do this is to use bracket notation and attach it to an existing object. For example, you could make it a global variable by attaching it to the global object:

global[settings.slug] = new Schema({
  title   : String
, content : String
});

global['foo'];  // your Schema object
foo;  // automatically will cascade to the global window variable global['foo']
