# `setunion` Function
|
|
|
|
The `setunion` function takes multiple sets and produces a single set
|
|
containing the elements from all of the given sets. In other words, it
|
|
computes the [union](https://en.wikipedia.org/wiki/Union_\(set_theory\)) of
|
|
the sets.
|
|
|
|
```hcl
|
|
setunion(sets...)
|
|
```
|
|
|
|
## Examples
|
|
|
|
```
|
|
> setunion(["a", "b"], ["b", "c"], ["d"])
|
|
[
|
|
"d",
|
|
"b",
|
|
"c",
|
|
"a",
|
|
]
|
|
```
|
|
|
|
The given arguments are converted to sets, so the result is also a set and
|
|
the ordering of the given elements is not preserved.
