in a function you can use error() for break, return for continue.

function foobar_with_continue_support()
    for i = 1,9 do
        if aaa then
            break
        end
        if bbb then
            continue
        end
    end
end

function foobar_without_continue_support()
    for i = 1,9 do
        if not pcall(function
            if aaa then
                error()
            end
            if bbb then
                return
            end
            end) then
            break
        end
    end
end
