»keys
Function
keys
takes a map and returns a list containing the keys from that map.
The keys are returned in lexicographical order, ensuring that the result will be identical as long as the keys in the map don't change.
»Examples
> keys({a=1, c=2, d=3}) [ "a", "c", "d", ]
> keys({a=1, c=2, d=3})
[
"a",
"c",
"d",
]
»Related Functions
values
returns a list of the values from a map.
