String concatenation
JSONiq follows the W3C standard for string concatenation. The following explanations, provided as an informal summary for convenience, are non-normative.
Two strings or more can be concatenated using the concatenation operator.
Example 46. String concatenation
"Captain" || " " || "Kirk"
Result (run with Zorba): Captain Kirk
An empty sequence is treated like an empty string.
Example 47. String concatenation with the empty sequence
"Captain" || () || "Kirk"
Result (run with Zorba): CaptainKirk
