Learn the basics of Elixir, along with advanced concepts such as OTP servers and multiple processes.

Become an Elixir Programmer

In this module, we’ll learn everything we need to know to start working with Elixir, including processing collections, using multiple tools, and working with OTP servers. Programmers usually learn by writing code, and that’s exactly how this module will also work. We'll practice a lot of coding examples that will help us get a strong grip on Elixir.

Our Fibonacci code is really inefficient. To calculate `fib(5)`, we calculate this:

Look at all that duplication. If only we could cache the intermediate values. As we know, Elixir modules are basically buckets of functions—they can’t hold state. But processes can hold state. And Elixir comes with a library module called `Agent` that makes it easy to wrap a process containing state in a nice module interface. Don’t worry about the details of the code because we’ll cover it in the coming lessons. For now, just see how processes are among the tools we use to add persistence to Elixir code.
