# `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
|
|
|
|
```shell-session
|
|
> keys({a=1, c=2, d=3})
|
|
[
|
|
"a",
|
|
"c",
|
|
"d",
|
|
]
|
|
```
|
