<p>
The <a href="https://hexdocs.pm/gleam_stdlib/gleam/list.html"><code>gleam/list</code></a>
standard library module contains functions for working with lists. A Gleam
program will likely make heavy use of this module.
</p>
<p>
<a href="https://hexdocs.pm/gleam_stdlib/gleam/list.html#map"><code>map</code></a>
makes a new list by running a function on each element in a list.
</p>
<p>
<a href="https://hexdocs.pm/gleam_stdlib/gleam/list.html#filter"><code>filter</code></a>
makes a new list containing only the elements for which a function returns
true.
</p>
<p>
<a href="https://hexdocs.pm/gleam_stdlib/gleam/list.html#fold"><code>fold</code></a>
combines all the elements in a list into a single value by running a function
left-to-right on each element, passing the result of the previous call to the
next call.
</p>
<p>
It's worth getting familiar with all the functions in this module when writing
Gleam code.
