-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>
-```
