- Most commonly functions in the - gleam/list - module are used to iterate across a list, but at times you may prefer - to work with the list directly. -

-

- Gleam doesn't have a looping syntax, instead iteration is done through - recursion and pattern matching. -

-

- The [first, ..rest] pattern matches on a list with at least one - element, assigning the first element to the variable first and - the rest of the list to the variable rest. - By using this pattern and a pattern for the empty list [] a - function can run code on each element of a list until the end is reached. -

-

- This code sums a list by recursing over the list and adding each int to a - total argument, returning it when the end is reached. -
