javascript:js_expression//1

Emit a single JSON argument. Expression is one of:

Variable: Emitted as Javascript null
List: Produces a Javascript list, where each element is processed by this library.
object(Attributes): Where Attributes is a Key-Value list where each pair can be written as Key-Value, Key=Value or Key(Value), accomodating all common constructs for this used in Prolog. $ { K:V, ... } Same as object(Attributes), providing a more JavaScript-like syntax. This may be useful if the object appears literally in the source-code, but is generally less friendlyto produce as a result from a computation.
Dict: Emit a dict as a JSON object using json_write_dict/3.
json(Term): Emits a term using json_write/3.
@(Atom): Emits these constants without quotes. Normally used for the symbols true, false and null, but can also be use for emitting JavaScript symbols (i.e. function- or variable names).
Number: Emited literally
symbol(Atom): Synonym for @(Atom). Deprecated.
Atom or String: Emitted as quoted JavaScript string.
