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
choice	Return a random item from a tuple.
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.
max	Returns the maximum value from all values in the list.
min	Returns the minumum value from all values in the 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.
