# wait / don't wait
wait = (t=0) -> (f) -> setTimeout f, t
async = (f) -> setTimeout f, 0

# simple shortcut
log = console.log

class Main
  compute: (a,b) -> a*b + a*b

  example1: -> 
    # schedule functions to be executed 
    wait(500) -> log "hello"
    wait(1000) -> log "world"

  # example2 will be executed as soon as possible
  example2: (txt) -> async ->
    log "started"
    log "finished"

  # mix everything. this time using fat arrows
  example3: (cb=->) => wait(4000) =>
    log "long computation"
    result = @compute()
