Read OriginalThis article provides a detailed guide to the Iterator design pattern in JavaScript. It defines the pattern, explains its purpose for sequential access without exposing underlying data structures, and includes a practical code example demonstrating an iterator for traversing an array with custom logic (e.g., every third element). It covers methods like next, hasNext, rewind, and current, highlighting use cases like asynchronous iteration.
