/xp add @s 30 levels

Adds 30 experience levels to yourself.

/xp set @a 0 points

Resets the experience points (within current level) for all players to 0.

/xp query @p levels

Queries and displays the nearest player's current level.

Confusing points and levels, points fill the bar within a level, levels are the number shown on the bar.
Using /xp set with points above the threshold for the current level, each level requires a different number of points.

The /xp command is functionally identical to /experience. Both are valid aliases in Java Edition.
