Does anyone have a good example for updating an existing contact through JavaScript?

I can use the Contact Id or the Email as the Id value.

You have a good example on the [documentation](https://developers.hubspot.com/docs/reference/api/crm/objects/contacts#patch-%2Fcrm%2Fv3%2Fobjects%2Fcontacts%2F%7Bcontactid%7D) to update a contact (click on “Node” on the right to have the example code in javascript, because you can only do it in backend and not in frontend). You have to use the contactId.
