    23  In this context, *safe* means the string encapsulates a known safe EcmaScript5 Expression (e.g., `(x + y * z())`).
    24  
    25  Template authors are responsible for ensuring that typed expressions do not break the intended precedence and that there is no statement/expression ambiguity as when passing an expression like `{ foo:bar() }\n['foo']()`, which is both a valid expression and a valid program with a very different meaning.
    26  
    27  Example: Given `hash = "619c16f"` defined in the front matter of your `.md` file:
    28  
    29  * <span class="good">`<script>var form_{{ .Params.hash | safeJS }};…</script>` &rarr; `<script>var form_619c16f;…</script>`</span>
    30  * <span class="bad">`<script>var form_{{ .Params.hash }};…</script>` &rarr; `<script>var form_"619c16f";…</script>`</span>
