Encapsulates a sequence of characters meant to be embedded between quotes in a JavaScript expression. Use of this type presents a security risk: the encapsulated content should come from a trusted source, as it will be included verbatim in the template output.
  
Without declaring a variable to be a safe JavaScript string:

```go-html-template
{{ $title := "Lilo & Stitch" }}
<script>
  const a = "Title: " + {{ $title }};
</script>
```

Rendered:


```html
<script>
  const a = "Title: " + "Lilo \u0026 Stitch";
</script>
```

To avoid escaping by Go's [html/template] package:

```go-html-template
{{ $title := "Lilo & Stitch" }}
<script>
  const a = "Title: " + {{ $title | safeJSStr }};
</script>
```

Rendered:

```html
<script>
  const a = "Title: " + "Lilo & Stitch";
</script>
```
