/** * Checks if a given value is a plain object. * * A plain object is an object created by the `{}` literal, `new Object()`, or * `Object.create(null)`. * * This function also handles objects with custom * `Symbol.toStringTag` properties. * * `Symbol.toStringTag` is a built-in symbol that a constructor can use to customize the * default string description of objects. * * @param {any} [object] - The value to check. * @returns {boolean} - True if the value is a plain object, otherwise false. * * @example * console.log(isPlainObject({})); // true * console.log(isPlainObject([])); // false * console.log(isPlainObject(null)); // false * console.log(isPlainObject(Object.create(null))); // true * console.log(isPlainObject(new Map())); // false */ declare function isPlainObject(object?: any): boolean; export { isPlainObject };
