/** * Checks if a given path exists within an object. * * You can provide the path as a single property key, an array of property keys, * or a string representing a deep path. * * If the path is an index and the object is an array or an arguments object, the function will verify * if the index is valid and within the bounds of the array or arguments object, even if the array or * arguments object is sparse (i.e., not all indexes are defined). * * @param {object} object - The object to query. * @param {PropertyKey | PropertyKey[]} path - The path to check. This can be a single property key, * an array of property keys, or a string representing a deep path. * @returns {boolean} Returns `true` if the path exists in the object, `false` otherwise. * * @example * * const obj = { a: { b: { c: 3 } } }; * * has(obj, 'a'); // true * has(obj, ['a', 'b']); // true * has(obj, ['a', 'b', 'c']); // true * has(obj, 'a.b.c'); // true * has(obj, 'a.b.d'); // false * has(obj, ['a', 'b', 'c', 'd']); // false * has([], 0); // false * has([1, 2, 3], 2); // true * has([1, 2, 3], 5); // false */ declare function has(object: unknown, path: PropertyKey | readonly PropertyKey[]): boolean; export { has };
