Depending on your environment, here is how you can build it: 1. Identify the Data Structure
You must have a way to sort your packages, usually by a version_number , created_at timestamp, or a defined order_id . 2. Logic Implementation
Retrieve the package with the highest ID or timestamp that is still strictly less than the current one. в†ђ Previous Package
To create a feature (often stylized as "← Previous Package" in UI components), you typically need to implement a navigation logic that identifies the chronological or sequential predecessor of the current item.
In systems like JD Edwards EnterpriseOne , features are often "assembled" into packages. A "Previous" button allows users to step back through the assembly director. 4. Advanced: "Replace Previous" Logic Depending on your environment, here is how you
Use a clear arrow symbol (← or ← ) to indicate direction.
const currentIndex = packages.findIndex(p => p.id === currentId); const previousPackage = currentIndex > 0 ? packages[currentIndex - 1] : null; Use code with caution. Copied to clipboard 3. UI/UX Design Logic Implementation Retrieve the package with the highest
