Javascript use variable as object name

How do I get JS to treat a string as a reference to a previously defined object? Simplified:

var myObject = new MyObject();  var myString = "myObject";  var wantThisToWork = myString.myproperty;

If the variable is in the global scope, you can access it as a property of the global object

var a = "hello world"; var varName = "a"; console.log( window[varName] ); // outputs hello world console.log( this[varName] ); // also works (this === window) in this case 

However, if it's a local variable, the only way is to use eval (disclaimer)

function () {   var a = "hello world";   var varName = "a";   console.log( this[varName] ); // won't work   console.log( eval(varName) ); // Does work } 

Unless you can put your dynamic variables into an object and access it like a property

function () {   var scope = {     a: "hello world";   };   var varName = "a";   console.log( scope[varName] ); // works }
