Object functions

These functions can be used when working with, and manipulating data objects.

object::entries

Available since: v1.1.0

The object::entries function transforms an object into an array with arrays of key-value combinations.

API DEFINITION
object::entries(object) -> array

The following example shows this function, and its output, when used in a RETURN statement:

RETURN object::entries({
  a: 1,
  b: true
});

[
  [ "a", 1 ],
  [ "b", true ],
]

object::from_entries

Available since: v1.1.0

The object::from_entries function transforms an array with arrays of key-value combinations into an object.

API DEFINITION
object::from_entries(array) -> object

The following example shows this function, and its output, when used in a RETURN statement:

RETURN object::from_entries([
  [ "a", 1 ],
  [ "b", true ],
]);

{
  a: 1,
  b: true
}

object::keys

Available since: v1.1.0

The object::keys function returns an array with all the keys of an object.

API DEFINITION
object::keys(object) -> array

The following example shows this function, and its output, when used in a RETURN statement:

RETURN object::keys({
  a: 1,
  b: true
});

[ "a", "b" ]

object::len

Available since: v1.1.0

The object::len function returns the amount of key-value pairs an object holds.

API DEFINITION
object::len(object) -> number

The following example shows this function, and its output, when used in a RETURN statement:

RETURN object::len({
  a: 1,
  b: true
});

object::values

Available since: v1.1.0

The object::values function returns an array with all the values of an object.

API DEFINITION
object::values(object) -> array

The following example shows this function, and its output, when used in a RETURN statement:

RETURN object::values({
  a: 1,
  b: true
});

[ 1, true ]

Method chaining

Available since: v2.0.0

Method chaining allows functions to be called using the . dot operator on a value of a certain type instead of the full path of the function followed by the value.

-- Traditional syntax
object::values({
  a: 1,
  b: true
});

-- Method chaining syntax
{
  a: 1,
  b: true
}.values();

Response
[
  1,
  true
]

This is particularly useful for readability when a function is called multiple times.

-- Traditional syntax
array::max(object::values(object::from_entries([["a", 1], ["b", 2]])));

-- Method chaining syntax
object::from_entries([["a", 1], ["b", 2]]).values().max();

Response
2
