Course Overview

The Open Telecom Platform (OTP) is a process-oriented design environment that Elixir inherits from Erlang, the VM in which Elixir executes. This process-oriented design and communication framework make programming in Elixir a unique challenge. In this course, you’ll learn about the design considerations needed to build and design Elixir projects effectively. You’ll learn in detail about the Erlang virtual machine and the project components. You’ll review Elixir data types to identify the correct data layer...Show More
