254-283: Optimizeddiffmethod to calculate 'latestItem' only once per fetch items.This change effectively optimizes the performance by reducing redundant calculations. The introduction of
latestItemto store the latest item and the conditional check to only calculate it once per set of fetch items is a good use of resources, aligning with the objectives of PR #699 and Issue #698.Tools

254-283: Optimize the handling oflatestItemto reduce redundant calculations.The implementation of
latestItemto determine the most recent item is correct. However, consider refactoring the loop to avoid recalculatinglatestItemmultiple times. You can calculate it once outside the loop and then reference it inside the loop as needed. This change would align with the PR's goal of reducing redundant calculations.Additionally, the variable
isLatestItemshould be declared asconstsince it is not reassigned. This change was suggested by the static analysis tool and is still applicable here.- let latestItem: BinaryItem | undefined; - for (const item of fetchItems) { - if (!latestItem) { - latestItem = sortBy(fetchItems, ['date']).pop(); - } + const latestItem = sortBy(fetchItems, ['date']).pop(); + for (const item of fetchItems) {
