In the world of Roblox development, "FE" stands for Filtering Enabled. This is the security protocol that ensures actions taken by a player (the client) don't automatically replicate to everyone else on the server unless the developer allows it.
; // Usage: copyToClipboard('Hello FE world!');
Check email formats, password strength, or required fields before submission.
For developers, the lesson is simple: If your server trusts the client's input without checking it, an FE script will eventually find that hole.
