Dict module

The gleam/dict standard library module defines Gleam's Dict 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.

new and from_list can be used to create new dicts.

insert and delete are used to add and remove items from a dict.

Like lists, dicts are immutable. Inserting or deleting an item from a dict will return a new dict with the item added or removed.

Dicts are unordered! If it appears that the items in a dict are in a certain order, it is incidental and should not be relied upon. Any ordering may change without warning in future versions or on different runtimes.
