+ Lists are ordered collections of values. +

+

+ List is a generic type, having a type parameter + for the type of values it contains. A list of ints has the type + List(Int), and a list of strings has the type + List(String). +

+

+ Lists are immutable single-linked lists, meaning they are very efficient to + add and remove elements from the front of the list. +

+

+ Counting the length of a list or getting elements from other positions in the + list is expensive and rarely done. It is rare to write algorithms that index + into sequences in Gleam, but but when they are written a list is not the right + choice of data structure. +
