Deleting a document from a mongodb collection

I have a collection called customers and it contains documents. I have written a function to delete a document using the field and its value which takes as arguments. But it doesn't remove any customer as expected. Can anybody show me where I have gone wrong?

function (fieldName, value) {
  db.customers.remove({x : y});
}

I called the function from the mongo terminal as below.

db.loadServerScripts();
removeDocument("firstName", "Sam");

Thanks

db.collection.remove is deprecated so use deleteOne or deleteMany(For deleting multiple documents)

Rewrite your function so that the arguments become part of the query object. You can do this using either computed property or bracket notation.

Using computed property:

function removeDocument(fieldName, value) {
    db.customers.remove({[fieldName]: value});
}

Using bracket notation

function removeDocument(fieldName, value) {
    var query = {};
    query[fieldName] = value;
    db.customers.remove(query);
}
