Through this exercise, I developed a stronger understanding of building interactive web applications that support customer purchasing workflows. I reinforced core JavaScript concepts from earlier lessons, including variables, numerical operations, querySelectorAll, functions, and dynamic data insertion, while also expanding my skill set with more advanced techniques.
I gained practical experience working with methods such as parseFloat, focus, minimumFractionDigits, maximumFractionDigits, nextSibling, and nodeValue. In addition, I implemented form validation and user experience improvements, including customizing default credit card messages, verifying credit card inputs for validity, and enhancing real-time interaction within the interface.
Overall, this project strengthened my ability to build more robust, user-friendly, and data-driven web applications.
