I guess I will add an input in the playground and copy its content to an extra wasm memory page. Then I'll track the input's index with a new local. I realized after coding that first version that most brainfuck programs run indefinitely. Apart from Hello World, I didn't find lots of program I could run synchronously. Making it asynchronous sounds like a tough job.
