hi i want to show console.log this situation..

if lasdId value is {}

i want to show console.log("hello");

but it doesn't work... how can i fix my code??

this is my code

    router.post('/related', async (req, res, next) => {
      
      try {
        // const lastId = parseInt(req.query.lastId, 10);
      const lastId = req.body;
      console.log("lastId:::::::::::::::::::::::",lastId);
    

      if (lastId === {}) {
        console.log("hello!");
        // where.id = { [Op.in]: followings.map((v) => v.id).filter(value => value < lastId)}
        // console.log("where:::::::::::::::::",where);
      }

i think the reason why console.log doesn't show up is that lastID type is uncorrect... then how can i fix type?

The value of lastId is not {}, so the log is ignored – Andrew Mar 03 '21 at 10:08
then how can i fix?? undefinde?? – jack volten Mar 03 '21 at 10:10
what's the value of lastId? – Andrew Mar 03 '21 at 10:10
It seems that the condition never applies, console.log(lastId) just before the if statement, then you would probably understand why the log(hello) doesnt appear. – MrJami Mar 03 '21 at 10:10
Yeah, you should try what MrJami suggested – Andrew Mar 03 '21 at 10:10

check if `Object.keys`. `if (Object.keys(last).length === 0) { console.log("Hello");}` – sourav satyam Mar 03 '21 at 10:11
