What's the standard naming convention for a property's backing field?

Background

I'm wanting to follow the most commonly-practised naming conventions for TypeScript. I've noticed that the official website shows code examples featuring Pascal-case for types and modules and camel-case for just about everything else.

Example

I'm currently implementing a property that encapsulates a backing value:

class SomeClass {
    get status() {
        return statusBackingField;
    }
    set status(newValue: Status) {
        statusBackingField = newValue;
        //Do other work here
    }

    statusBackingField: Status;
}

Problem

The name of the property is status. In C#, I would normally name the property Status and the backing value status. Since the convention is to use camel-case for properties, this doesn't work. I'm not sure which convention I should use for consistency with other TypeScript code in general.

Question

Other languages, such as C# and Java, seem to have official or de facto standard conventions. Is there any such authoritative or de facto standard convention for naming backing fields in TypeScript?

Notes

For the close-voters: please note that I'm not looking for opinions. I'm looking for objective information as requested in the summarised question above.

I think it's safe to say at this stage that there is no standard.

If someone can point me to an authoritative standard or evidence of a de-facto standard, then I may consider accepting their answer instead.
