Actually, it might be possible to do it with JsInterop only:
class Globals {
@JsMethod(namespace=GLOBAL)
public native Object eval(String expresion);
@JsOverlay
public native boolean isVariableDefined(String varName){
return Boolean.TRUE.equals(eval("!!window['"+varName+"']"));
}
}
I guess, you can also use JSON.safeEval() ... but we dont know if will
survive in J2CL.
