We can also use the PATCH method to update a resource. The difference

between the PUT and PATCH methods is: the PUT method updates the

whole resource, whereas PATCH is used for a partial update on resources.

}, function(error, user){

if (error) { console.error(error); }

res.send({ success: true })

})

})
