Tuples
Explore how tuples function as fixed-length, immutable data structures in Elixir. Understand their common applications like tagging data and grouping related values, along with their limitations such as lack of labels and inefficiency with appended operations. This lesson helps you recognize when to use tuples versus other data types like maps or lists.
We'll cover the following...
Tuples are fixed-length data structures. Like all Elixir data structures, they are immutable. We can access or pattern match against any element of the tuple efficiently. This lesson will show you the types of problems we can generally solve with tuples. Let’s take a look at them.
Good tuples
Generally, think of tuples as structures where the position within the tuple means something. Coordinates, {key, value} pairs from maps, and {city, state} pairs are all ...
