how to delete using moongoose code example

Example 1: mongoose find by and delete

Campground.findByIdAndRemove(req.params.id, function(err){
      if(err){
          res.redirect("/campgrounds");
      } else {
          res.redirect("/campgrounds");
      }
   });

Example 2: mongoose remove data

Remove is deprecated - use delete
Update for Mongoose v5.5.3 - remove() is now deprecated.
Use deleteOne(), deleteMany() or findOneAndDelete() instead.
