Worked on the exelearning/exelearning repository to enhance the reliability and predictability of the authoring interface by addressing issues with block ordering in the workarea. Focused on front end development using JavaScript, the approach involved refining the insertion logic and introducing a utility function to sort blocks by their IDs. This deterministic ordering ensured that blocks consistently appeared in the same sequence across insertions and reloads, reducing confusion for users and streamlining quality assurance. The work centered on improving the user interface’s stability and maintainability, leveraging core JavaScript skills to deliver a more predictable and robust editing experience.
