While Loop

Simple while loop:

import While

def demo_global() do
  cnt = :counters.new(1, [:atomics])
  while :counters.get(cnt, 1) < 10 do
    :counters.add(cnt, 1, 1)
  end

  IO.puts("Current value is #{:counters.get(cnt, 1)}")
end

def demo_local() do
  cnt = 1
  cnt = while cnt, cnt < 10 do
    cnt + 1
  end

  IO.puts("Current value is #{cnt}")
end
