Metacompilation

Metacompilation is like when you are playing a game and you want to earn points, like coins or stars. Metacompilation is when a computer program takes another program and uses it to make something new. Metacompilation allows a computer to take a program and break it apart, then put it back together in a better way. This can make the programs run faster or more efficiently, or can even make them do something totally new. So when computers use metacompilation to create new programs, it's like they're earning points in a game!
