I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
CapeJS
CapeJS is a NeoForge mod for Minecraft 1.21 that allows you to add custom capes to users using KubeJS. It's intended purpose is for modpack developers to give capes to pack developers, pack completionists, friends, etc. Adding capes is done through a client script, which is detailed here. The cape texture is also used to replace the elytra texture!
