I'd like to check which elements are equal in my two arrays, but can't get it working.

This is my code:

for (var i; i < bombs.length; i++) {

    for (var j; j < bombsDb.length; j++) {

        if (bombs[i].name === bombsDb[j].address) {

            console.log(bombs[i].name);

        } else {

            console.log(non-equal elements);

        }

    }

}

So the first array contains objects from the google places api and the second one contains data from my database.

Thanks in advance!

You have to initialize i and j;

   for (var i = 0; i < bombs.length; i++) {

        for (var j = 0; j < bombsDb.length; j++) {

            if (bombs[i].name === bombsDb[j].address) {

                console.log(bombs[i].name);

            } else {

                console.log(non-equal elements);

            }

        }

    }
