Implement Erlang Standard Library calls in Elixir Standard Library

從 issue 中選擇一個未勾選的函式，並先閱讀其連結的 Erlang 文件。在 src/javascript/lib/core/erlang_compat 中實作它，為該函式新增測試，並在開啟 pull request 之前確認其行為是否符合 Erlang 文件。

Below is a list of all the known Erlang standard library functions found in Elixir's Standard Library that have not been implemented in some way yet in ElixirScript. Implementations should go here

For anyone looking to implement a function the steps would be to:

• Pick a function or functions from the list below
• Implement the function(s) in JavaScript according to the Erlang docs
• Add tests for the function(s) implemented
• Make Pull Request

Then we can check off those functions is the list below
