i come from a ruby background and the concept of Set is something im not familiar with.
How is it different from a regular Array, in what scenarios should i be choosing one over the other?

They are similar but a Set
is unordered and does not contain duplicates. An array can contain duplicates and order depends on the order items were inserted.
However, the current implementation of Set
causes it to be ordered. This is just an implementation detail and should not be relied upon if you need a specific order.

There could be a page in the book explaining the difference between:
Array
Set
Tuple
StaticArray
Slice
Deque

it’s the same as in Ruby, Ruby also has Set
easy confuse with NamedTuple and Hash
{a:1}
and {:a => 1}
in ruby, its same.
