Gain hands-on experience working with processing collections and utilizing Elixir's concepts to build robust applications.

Test Your Web Applications with Elixir

Elixir offers a practical approach to functional programming, emphasizing immutable state and leveraging the extensive range of packages, modules, and tools available in Erlang. In this module, we will gain hands-on experience working with Elixir, covering topics such as processing collections and control flows. With a focus on practical learning, this module provides abundant coding examples to strengthen our proficiency in Elixir and ensure a solid understanding of the language.

What will be the output of the following code?

```
list = [9,19,29,39]
Enum.map(list, &(&1*2 + 10))
```


What will be the output of the following code?
<pre><code>list = [9,19,29,39]
Enum.map(list, &amp;(&amp;1*2 + 10))
</code></pre>

Which stream takes a function and invokes it each time a new value is wanted?

Which stream takes a function and invokes it each time a new value is wanted?

In the `Collectable` protocol, given a collection, you can get the elements. The `Enumerable` protocol allows you to build a collection by inserting elements into it.

In the `Enumerable` protocol, given a collection, you can get the elements. The `Collectable` protocol allows you to build a collection by inserting elements into it.

In the `Enumerable` protocol, you can convert collection to elements as well as from elements to collection. The `Collectable` protocol allows you to build a collection by inserting elements into it.

The `Enumerable` protocol  allows you to build a collection by inserting elements into it. The `Collectable` protocol allows you to convert collection to elements as well as from elements to collection.

What’s the difference between the `Collectable` and `Enumerable` protocols?

What’s the difference between the <code>Collectable</code> and <code>Enumerable</code> protocols?

`["J", "o", "h", "n", " ", "D", "e", "n", "v", "e", "r"]`

`["J", "o", "h", "n", "D", "e", "n", "v", "e", "r"]`

`["j", "o", "h", "n", " ", "d", "e", "n", "v", "e", "r"]`

`["J", "o", "h", "n", " ", "d", "e", "n", "v", "e", "r"]`

What’s the output of `for << abc <- "John Denver" >>, do: <<abc>>`?

What’s the output of <code>for &lt;&lt; abc &lt;- &quot;John Denver&quot; &gt;&gt;, do: &lt;&lt;abc&gt;&gt;</code>?
