  "account": "JavaScript offers a variety of built-in methods to manipulate arrays efficiently. These methods enable developers to perform tasks such as adding, removing, updating, or retrieving elements, transforming arrays, and iterating through them.\n\n1. The toString() method converts an array into a comma-separated string without modifying the original array. This method is useful for representing the array's content as a string. For instance, if we have an array of names like [Jaisurya, Dinesh, Ramesh], calling names.toString() would output \"Jaisurya, Dinesh, Ramesh\".\n\n2. The at() method retrieves an element from an array based on its index. It supports both positive and negative indices. Positive indices start from the beginning of the array (0-based), while negative indices count from the end. For example, given an array names = [Jaisurya, Ramesh, Dinesh], names.at(1) would return \"Ramesh\", and names.at(-1) would return the last element, \"Dinesh\".\n\n3. The forEach() method is a built-in method that iterates over each element in an array and executes a provided function for each element. Unlike some other methods, forEach() does not return a new array or alter the original array; its primary purpose is for iteration. Here's an example: with an array seasons = [\"spring\", \"summer\", \"winter\", \"autumn\"], seasons.forEach((season) => console.log(season)) would print each season name on a separate line.",
