Description: The Iterator pattern is a design pattern that provides a way to access the elements of an aggregate object sequentially without exposing its underlying representation. This pattern allows developers to traverse collections of objects uniformly, without needing to know the internal structure of the collection. In JavaScript, the Iterator pattern is commonly implemented through objects that contain methods to access elements one by one, facilitating iteration over data structures such as arrays, sets, or maps. One of the most notable features of the pattern is its ability to separate the iteration logic from the collection itself, promoting cleaner and more maintainable code. Additionally, the Iterator pattern is fundamental for the implementation of for…of loops and other control flow constructs in JavaScript, making it an essential tool for developers looking to write more readable and efficient code. In summary, the Iterator pattern not only enhances accessibility to the elements of a collection but also encourages encapsulation and separation of concerns in software design.
