Maps
Explore the behavior of Go maps, focusing on their undefined and random iteration order due to hash table implementation. Learn how to check for keys effectively to prevent bugs and understand the impact of map growth on iteration sequencing.

map iteration order is random (no really)
Technically map iteration order is “undefined”. Go maps use a hash
table internally so map iteration would normally be done in whatever
order the map elements are laid out in that table. This order can’t be relied on and changes as a hash table grow when new elements are added to the map. ...
