ELI5: Explain Like I'm 5

Performance

Performance is like how quickly and well you can do something.

For example, let's pretend we have two friends, Sally and Billy, who are racing to see who can run around the yard the fastest. Sally finishes running around the yard first and has a better performance because she was able to do it quickly.

In real life, performance can be lots of different things, such as how fast you can solve a math problem, how good you are at playing a sport, or even how quickly you can get dressed in the morning.

People often try to improve their performance by practicing or learning new ways to do things better. So just like Sally could practice running to get even faster, people can practice to get better at other things too!
