How to Create Objects Using Variable Strings as Class Names in JavaScript?

Assigning Variables to Class Names for JavaScript Object Creation

One of the commonly faced challenges in JavaScript is the task of creating objects using variable strings to define class names. Let's delve into a specific use case to better understand the issue and explore a potential solution.

The following snippet illustrates the desired yet syntactically incorrect approach:

<code class="javascript">// Define the class
MyClass = Class.extend({});

// Store the class name in a string
var classNameString = 'MyClass';

// Instantiate the object using the class name string
var myObject = new classNameString();</code>

To resolve this, we can utilize the following alternative syntax:

<code class="javascript">var myObject = window[classNameString];</code>

By accessing the window object, we can retrieve the object associated with the class name stored in the classNameString variable. This approach allows us to dynamically create objects using variable strings to represent class names, providing a flexible and adaptable solution for various scenarios in JavaScript development.
