I have a short question about `where`. How can I rewrite the code

```
  {{ $files := readDir $part }}

  {{ range $files }}
    {{ if eq (substr .Name -1 3) ".js" }}
      {{ .Name }}
    {{ end }}
  {{ end }}

```

to

```
{{ range where $files (substr .Name -1 3) ".js" }}

```

?

I can’t understand the correct `where` syntax.
