int main() {
    JSRuntime *rt = JS_NewRuntime();
    JSContext *ctx = JS_NewContext(rt);
    
    const char *code = "console.log('Hello from QuickJS!')";
    JSValue result = JS_Eval(ctx, code, strlen(code), "<input>", JS_EVAL_TYPE_GLOBAL);
    
    JS_FreeValue(ctx, result);
    JS_FreeContext(ctx);
    JS_FreeRuntime(rt);
