Map Methods

Maps (also known as dictionaries or objects) have specific built-in methods for extraction and checks.

Get Keys (key)

Extract all keys from a map into an array.

m = {"a": 1, "b": 2}
key(m) // ["a", "b"]

Get Values (val)

Extract all values from a map into an array.

m = {"a": 1, "b": 2}
val(m) // [1, 2]

Check if Key Exists (has)

Check if a specific key exists within a map. Returns a boolean.

m = {"name": "Zaky"}
has(m, "name") // t
has(m, "age")  // f

Length (len)

Get the number of key-value pairs in a map.

m = {"a": 1, "b": 2}
len(m) // 2
