Documentation​

Serializes a value with JSON serialization semantics and returns the resulting string.

Unlike $string(), this helper still applies JSON serialization to string inputs, so the returned value for a string includes JSON quotes. If prettify is true, the JSON output is indented. Functions serialize to an empty string, and undefined input returns undefined.

Examples​

Serialize a string value as JSON text​
