A FieldPath refers to a field in a document. The path may consist of a single field name (referring to a top-level field in the document), or a list of field names (referring to a nested field in the document).
Create a FieldPath by providing field names. If more than one field name is provided, the path will point to a nested field in a document.
const user = await firebase.firestore().doc('users/alovelace').get(); // Create a new field path const fieldPath = new firebase.firestore.FieldPath('address', 'zip'); console.log('Address ZIP Code', user.get(fieldPath));
Returns true if this
FieldPath is equal to the provided one.
isEqual(other: FieldPath): boolean;
