## -- 并发(Concurrency)
## ---------------------------
-# Elixir relies on the actor model for concurrency. All we need to write
-# concurrent programs in elixir are three primitives: spawning processes,
-# sending messages and receiving messages.
+# Elixir 依赖与actor并发模型。在Elixir编写并发程序的三要素:
+# 创建进程,发送消息,接收消息
# 启动一个新的进程使用`spawn`函数,接收一个函数作为参数
+
f = fn -> 2 * 2 end #=> #Function<erl_eval.20.80484245>
spawn(f) #=> #PID<0.40.0>
-# `spawn` returns a pid (process identifier), you can use this pid to send
-# messages to the process. To do message passing we use the `<-` operator.
-# For all of this to be useful we need to be able to receive messages. This is
-# achived with the `receive` mechanism:
+
+# `spawn` 函数返回一个pid(进程标识符),你可以使用pid向进程发送消息。
+# 使用 `<-` 操作符发送消息。
+# 我们需要在进程内接收消息,要用到 `receive` 机制。
