When rendering an optional numerical field, the safest way to check on its existence is:
{{if typeof $item.data.optional_field == "number"}}...{{/if}}(for other types, change the right side of the
== accordingly)The main problem with the way described in the doc is possible accidental name collision of the field's name with some other variable in the scope.
