Hello,

I’m reading a JSON file with

```
{{ range $item := getJSON "data/references.json" }} 

```

but I have got some keys with - e.g.

```
[
   { "id" : "mykey", "container-title" : "a container name" }
]

```

I can get access of the values by

```
$item.id

```

but not with

```
$item.container-title
$item.(container-title)
$item."container-title"

```

How can I get access to a key with a minus within the key name?

Thanks

Phil

thanks for this, works well, I undstand the “index” first in that way, that it works only for numerical values 🙂 and not also for string values

Index in this case is a built-in func in Go templates that works for both slices and maps.
