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