Elixir is a functional programming language that runs in the Erlang VM, a powerful environment to run distributed systems. This course uses Elixir because of its fun syntax, vibrant community, and production-ready tooling. Elixir syntax lets you focus on what’s important while learning functional programming.

Starting from scratch, you will learn the fundamentals of Elixir including expressions, modules, conditional statements, and recursion. Towards the end of the course, you will focus on more advanced material like higher-order functions, how to handle impure functions, and lastly how to design an application using Elixir and functional programming principles.

By the end, you will be able to write basic Elixir programs that follow the functional programming paradigm.

Lock mechanisms are needed for parallel work.

Variables are considered as the basic building blocks.

Which of the following statements about functional programming is correct?

Which of the following statements about functional programming is correct?

What would be stored in the variable `list` after the following code executes:

```Elixir
list = [3, 7, 9, 10] 
List.delete_at(list, -1)
```

What would be stored in the variable <code>list</code> after the following code executes:
<pre><code class="language-Elixir">list = [3, 7, 9, 10] 
List.delete_at(list, -1)
</code></pre>

The function’s result is affected only by the function’s arguments.

The function doesn’t generate effects beyond the value it returns.

Which of the following is **not** a property of pure functions?

Which of the following is not a property of pure functions?
