safeJS	Declares the provided string as a known safe JavaScript string.	functions	docs parent functions	strings	safeJS INPUT

In this context, safe means the string encapsulates a known safe EcmaScript5 Expression (e.g., (x + y * z())).

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.

Example: Given hash = "619c16f" defined in the front matter of your .md file:

• <script>var form_{{ .Params.hash | safeJS }};…</script> → <script>var form_619c16f;…</script>
• <script>var form_{{ .Params.hash }};…</script> → <script>var form_"619c16f";…</script>
