`Map` produces a new slice of values by mapping each value in the slice through a transform function.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
u "github.com/rjNemo/underscore"
|
|
)
|
|
|
|
func main() {
|
|
nums := []int{1, 2, 3}
|
|
toSquare := func(n int) int {
|
|
return n * n
|
|
}
|
|
fmt.Println(u.Map(nums, toSquare)) // {1, 4, 9}
|
|
}
|
|
```
