Introduction Return statements are critical in JavaScript for functions to send data back to the caller. When executed, they stop function execution and return a value to the calling code. This enables reusable logic that can calculate, manipulate, or process data in some way before sending it back. In this comprehensive 2845 word guide, we'll
