<p>
The
<a href="https://hexdocs.pm/gleam_stdlib/gleam/dict.html"
><code>gleam/dict</code></a
>
standard library module defines Gleam's <code>Dict</code> type and functions
for working with it. A dict is a collection of keys and values which other
languages may call a hashmap or table.
</p>
<p>
<a href="https://hexdocs.pm/gleam_stdlib/gleam/dict.html#new" target="_blank">
<code>new</code>
</a>
and
<a href="https://hexdocs.pm/gleam_stdlib/gleam/dict.html#from_list" target="_blank">
<code>from_list</code>
</a>
can be used to create new dicts.
</p>
<p>
<a href="https://hexdocs.pm/gleam_stdlib/gleam/dict.html#insert" target="_blank">
<code>insert</code>
</a>
and
<a href="https://hexdocs.pm/gleam_stdlib/gleam/dict.html#delete" target="_blank">
<code>delete</code>
</a>
are used to add and remove items from a dict.
</p>
<p>
Like lists, dicts are immutable. Inserting or deleting an item from a dict
will return a new dict with the item added or removed.
</p>
<p>
Dicts are unordered! If it appears that the items in a dict are in a certain
order this is incidental and should not be relied upon. Any ordering may
change without warning in future versions or on different runtimes.
