Transforms each input element into a tuple and splits results into parallel slices. Variants support arities from 2 to 9.
|
|
|
|
Variants: `UnzipBy2..UnzipBy9`
|
|
|
|
```go
|
|
type User struct{ ID int; Name string }
|
|
ids, names := lo.UnzipBy2([]User{{1,"a"},{2,"b"}}, func(u User) (int, string) {
|
|
return u.ID, u.Name
|
|
})
|
|
```
