Find looks through each value in the slice, returning the first one that passes a truth test (predicate), or the default
|
|
value for the type and an error if no value passes the test. The function returns as soon as it finds an acceptable
|
|
element, and doesn't traverse the entire slice.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
u "github.com/rjNemo/underscore"
|
|
)
|
|
|
|
func main() {
|
|
nums := []int{2, 4, 5, 6, 8, 0}
|
|
isOdd := func(n int) bool { return n%2 != 0 }
|
|
|
|
n, err := u.Find(nums, isOdd)
|
|
fmt.Println(n) // 5
|
|
fmt.Println(err) // nil
|
|
}
|
|
```
