<p>
The
<a href="https://hexdocs.pm/gleam_stdlib/gleam/list.html" target="_blank">
<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, the various functions
serving as different types of loops over lists.
</p>
<p>
<a href="https://hexdocs.pm/gleam_stdlib/gleam/list.html#map" target="_blank">
<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" target="_blank">
<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" target="_blank">
<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>
<a href="https://hexdocs.pm/gleam_stdlib/gleam/list.html#find" target="_blank">
<code>find</code>
</a>
returns the first element in a list for which a function returns
<code>True</code>.
</p>
<p>
It's worth getting familiar with all the functions in this module when writing
Gleam code, you'll be using them a lot!
