Protothreads

Protothreads are a way of writing code so that it runs more quickly and efficiently. They work by grouping short pieces of code together into "threads", or blocks that can be run at the same time. This way, the computer doesn't have to go through each line of code one-by-one - instead, it can group certain parts of the code together and run them all at once. This saves time and helps your computer work faster.
