# choose
`githbu.com/lestrrat-go/choose` is a simple tool that allows users to choose random
elements out of a container. It uses the new type parameters introduced in go 1.18
# Slice
Initialize a choose.SliceChooser:
```go
src := []int{....}
c := choose.Slice[int](src)
```
## Choose a random element from a slice
```go
elem := c.One()
```
## Choose N random elements from a slice
```go
elems := c.N(3)
```
# Map
Initialize a choose.MapChooser:
```go
src := map[string]int{...}
c := choose.Map[string,int](src)
```
## Choose a random element (as choose.MapElement) from a map
```go
elem := c.One()
fmt.Printf("%s -> %v", elem.Key, elem.Value)
```
## Choose N random elements (as []choose.MapElement) from a map
```go
elem := c.N(3)
```
