Hello, how can i evaluate an id from a json api ?

i have a list like this

```auto
visible_instructors:[{}]
[{
  "id": 0,
  "parent": 2,
  "name": "Grand Child 1"
}, {
  "id": 1,
  "parent": 2,
  "name": "Grand Child 2"
}]

```

so when i call it like that

```auto
{{ $json.visible_instructors[""0""].name }}

```

i get the error

```auto
 bad character U+005B '['  

```

i wonder how i could escape the 0 id

I’m not familiar with this syntax, is that some kind of `javascript`’s `map.filter()`?

This look like you are not targeting the `id` key here, but rather the index which coincidently in your example are the same.

In go Template, you cannot access an array element this way, you have to use [`index`](https://gohugo.io/functions/index-function/#readout):

```auto
{{ (index $json.visible_instructors 0).name }}

```
