Minecraft:Function tag (Java Edition)

A function tag is a group of functions. They can be called in the Template:Cmd command with Template:Cd, which runs all the functions specified in the tag in the order of their first appearance in a tag. If a function is referenced multiple times in a tag and its sub-tags, it is run once.

Moreover, functions tagged in the Template:Cd tag run every tick at the start of the tick and functions tagged in Template:Cd run once at the start of the tick after a server (re)load.

Template:Tag folder Data packs can define custom function tags.
