js_script(+String, +Options)

Evaluate String as JavaScript. This is designed to cooperate with string quasi quotations, so we can write e.g.,

:- use_module(library(strings)).
:- js_script({|string||
function myfunc(a)
...
|}).

The implementation uses =:/2, calling the JavaScript function eval().

[det]js_script(+String, +Options)

Evaluate String as JavaScript, for example for defining a function. This may be used together with the strings quasi quotation facility to easily support long strings that may also use double quotes.

:- use_module(library(strings)).
:- js_script({|string||
function myfunc(a)
...
|}).

Options is currently ignored. While this used to add a <script> node to the document it now uses (=:)/2 to evaluate the script. I.e. js_script is the same as:

?- _ := eval(String).
