REST API – PATCH – to Update some fields only in Mongo DB Record

PATCH request in REST API can be made to update particular fields in a particular record. It can alter certain fields without replacing entire record. Or like the PUT request it does not delete other fields that are not fed inputs. SO we can easily alter the necessary fields of a mongo db record.

    {title: req.params.articleTitle},
    {$set: req.body},
        res.send("Successfully updated article.");
