Anushka worked on the PolicyEngine/policyengine-app repository, focusing on improving the user interface for parameter display. She addressed a bug in the PolicyLeftSidebar by refining how parameters using bracket notation are sorted, ensuring that numerical indices are extracted and used for logical ordering. This adjustment, implemented in JavaScript, enhanced the predictability and consistency of parameter listings, directly improving data integrity and user experience. By updating the buildParameterTree function, Anushka ensured that bracketed parameters now appear in a sequence that matches their actual indices. Her work demonstrated attention to detail in front end development and careful handling of UI logic.
