Step-by-step explanation:
An example of a web application that I have built is an online e-commerce platform. The technologies used to build it were HTML, CSS, JavaScript, and PHP for the frontend, and MySQL for the backend database. When deciding on the tech stack, I considered factors such as the scalability of the platform, the ease of development, and the security measures required for handling user data and online transactions.
One consideration was the choice of the frontend framework. I chose to use HTML, CSS, and JavaScript because they are universally supported by web browsers and provided the flexibility and control I needed for the interface design and user experience. For the backend, I selected PHP and MySQL due to their compatibility, performance, and extensive community support for building dynamic web applications.
