```

### Usage
Here is a possible [program](TODO-LINK) to test your function :
```go
package main
import (
"fmt"
piscine ".."
)
func main() {
tab1 := []string{"Hello", "how", "are", "you"}
tab2 := []string{"This","1", "is", "4", "you"}
answer1 := piscine.CountIf(piscine.IsNumeric, tab1)
answer2 := piscine.CountIf(piscine.IsNumeric, tab2)
fmt.Println(answer1)
fmt.Println(answer2)
}
```
And its output :
```console
student@ubuntu:~/piscine/test$ go build
student@ubuntu:~/piscine/test$ ./test
0
2
student@ubuntu:~/piscine/test$
```
