The GeoService objectIds parameter is a convienance parameter for filtering features by unique-identifier. This could also be accomplished with use of the where parameter. This function transforms the objectIds parameter as part of the where parameter, so it can be more easily passed on to remote APIs.
const objectIds = '1,2,3';
const idField = 'id';
const where = 'foo=\'bar\'';
const whereClause = combineObjectIdsAndWhere({ objectIds, where, idField})
/*
Returns
"(id in (1,2,3)) AND (foo='bar')"
