tuple

All nested arrays are immutable and thus tuples.

list = [];
list.push(['this list will be nested and therefore convert to a tuple']);

// Check that the first item in `list` is indeed a `tuple`
assert(is_tuple(list[0]));

// Check that the `tuple` is indeed immutable
assert(is_err(try(list[0].push('cannot be added to a tuple'))));

A tuple only becomes a tuple when it is nested inside another tuple or list, which means the tuple will be immutable.

Functions

Function	Description

copy	Copy a tuple (same as dup unless a non-zero deep argument is used).
count	Returns the number of elements with a specified value in a tuple.
dup	Duplicate a tuple.
each	Iterate over all items in a tuple.
every	Check if all items pass a given test.
filter	Return a new list with items that pass a given test.
find	Return the first item that pass a given test.
find_index	Return the index of the first item that pass a given test.
first	Return the first item from a tuple.
flat	Return a new list with all tuple elements concatenated into it recursively up to a specified depth.
has	Return true if a given value is found in the tuple, or false if not found.
index_of	Return the index of a given value, or nil if not found.
is_unique	Returns true if each item in a tuple is unique or false if a duplicate is found.
join	Returns a string with all items joined.
last	Return the last item from a tuple.
len	Return the length of the tuple.
map	Return a new list with the results of calling a provided closure on every item.
map_id	Return a new list with the Ids for all the things in the original list.
map_type	Return a new list with each item of the original list converted to a typed-thing of the given Type.
map_wrap	Return a new list with the Ids for all the things in the original list.
reduce	Execute a reducer function on each item, resulting in a single output value.
reverse	Return a new list with the items in reverse order.
some	Check if at least one item passes a given test.
sort	Return a new sorted list.
sum	Returns the sum of all elements in a tuple.
unique	Returns a new list without duplicate items.
