Worked on the makeswift/makeswift repository to address a critical stability issue in the Element Tree reducer, focusing on improving data integrity and editor reliability. The solution involved refining the reducer’s logic to ensure that deleting a property from an element’s state no longer caused unintended deletions of the element or its children. By introducing clear distinctions between prop deletion and element deletion, the update prevented cascading lifecycle changes during prop edits. The work was implemented using TypeScript and leveraged state management techniques, with thorough testing in Jest to ensure runtime stability and maintainability of the element state within the editor environment.
