FUNCTION

# map.putAll

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

**Deprecated** (for removal): Use 'put\_all' instead

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

Since 0.9.0

**Alias of** [map.put\_all](https://docs.chromia.com/pages/rell-stdlib/-rell-system-library/root/map/put_all/)
