BrainScript provides a BF interpreter bf which can be used in interactive or batch mode, as well as a BF REPL brain.

bf can be used to batch process BF code, returning any resulting output as a string

const output: string = bf("++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.>---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++.")

console.log(output) // Hello World!\n

...but it also provides basic interactive capabilities for programs which require user input

// input.ts
console.log(bf(",."))
