FUNCTION

# map.put\_all

```signature
function put_all(map: map<-K, -V>): unit
```

Update this map with the entries from another map. Where a key is found in both this and the passed
map, the corresponding value in the passed map overwrites the value in this map. In other words,
this is a *right-biased* operation.

**Parameters**

* **map** — the map whose entries are used to update this map
