JavaScript Proxy Object Lab

In this lab, you will explore the JavaScript Proxy object by creating a proxy object with a custom handler. This handler will intercept the 'get' operation on the object's property and return the value in uppercase if the property is msg. Otherwise, it will return the original value for other properties.

You will create a file named proxy.js and follow the challenges to construct the Proxy, target, and handler objects. Use ESM syntax for import and export.
