Aruka Konys developed a front-end JavaScript exercises interface for the Azamat313/1-23 repository, delivering a single, self-contained HTML file named aruka.html. The interface featured three interactive tasks: a timer displaying elapsed time, a utility for sorting names by length, and a prime number checker. Using HTML, CSS, and JavaScript, Aruka focused on DOM manipulation and event handling to create a reusable tool that accelerates frontend prototyping and onboarding. The work provided a tangible example of core front-end development skills, enabling rapid validation of JavaScript concepts and supporting developer demos, with a clear emphasis on maintainability and practical business value.
