🚀 Dynamic Updates with $set

Want to update a field, but the field name is stored in a variable? No problem!
MongoDB lets you use dynamic keys for ultra-flexible updates:

{ [key]: value }

• key: The variable holding your field name.
• value: The new value you want to set.

💡 This trick lets you build smart, adaptable update operations—perfect for apps that need to move fast and stay flexible!
