/** * Recursively assigns default values to an `object`, ensuring that certain properties do not remain `undefined`. * It sets default values for properties that are either `undefined` or inherited from `Object.prototype`. * * Similar to `defaults` but recursively applies default values to nested objects. * Source objects are applied in order from left to right, and once a property has been assigned a value, * any subsequent values for that property will be ignored. * * Note: This function modifies the first argument, `object`. * * @template T - The type of the object being processed. * @param {any} target - The target object that will receive default values. * @param {any[]} sources - One or more source objects that specify default values to apply. * @returns {any} The `object` that has been updated with default values from all sources, recursively merging nested objects. * * @example * defaultsDeep({ a: { b: 2 } }, { a: { b: 3, c: 3 }, d: 4 }); // { a: { b: 2, c: 3 }, d: 4 } * defaultsDeep({ a: { b: undefined } }, { a: { b: 1 } }); // { a: { b: 1 } } * defaultsDeep({ a: null }, { a: { b: 1 } }); // { a: null } */ declare function defaultsDeep(target: any, ...sources: any[]): any; export { defaultsDeep };
