Here's an example:
Object.defineProperty(js.global, "prop", {
get : function () {
return "hello, world";
}
});
bbs.replace_text("Pause", "@JS:" + "prop@"); // @-code split for posting
console.pause(); // will invoke the global 'prop' getter function
In this example, the "prop" getter function could do more stuff and just return an empty string if that's what's desired.
