Conclusion

When dealing with JavaScript arrays that may have prototype properties, it’s essential to understand how to print only the original properties. By using the hasOwnProperty method, you can iterate through an array while excluding any added prototype properties, ensuring that you obtain the intended results. This knowledge will help you maintain code clarity and avoid unexpected behavior in your JavaScript projects.

JavaScript arrays are versatile data structures used to store collections of items. When you want to iterate through the elements of an array, it’s common to use loops like for, for…of, or forEach. However, there’s a nuance when it comes to iterating through arrays that have additional properties added through their prototype.

In this article, we will explore how to print only the original properties of an array, excluding any prototype properties, ensuring a clean and accurate output.
