Pre-calculate `_searchStr`, `_isNew`, and `_formattedDate` once during initial data load in `prepareSearchIndex`. Utilize these pre-computed properties with explicit early returns in the `renderPDFs` filtering loop and inside `createPDFCard`, avoiding expensive string concatenations, `Date` instantiations, and full-iteration `Array.filter` checks on every user interaction.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |
💡 What: Added a
prepareSearchIndexfunction that pre-calculates expensive derived properties (_searchStr,_isNew,_formattedDate) on PDF objects directly after data load. Updated therenderPDFsfilter loop to use explicit early returns and these pre-calculated properties instead of recalculating strings inline. RefactoredcreatePDFCardto consume these values rather than instantiating newDateobjects per card.🎯 Why: Instantiating
Dateobjects and repeatedly concatenating/lowercasing large strings within high-frequency loops (like typing in the search bar or filtering a large dataset) causes measurable UI slowdowns and main thread blocking.📊 Impact: Significantly reduces processing overhead per re-render by short-circuiting filtering conditions and avoiding repeated object instantiations and string conversions, ensuring a smoother typing and filtering experience for users.
🔬 Measurement: The optimization can be verified by observing the responsiveness of the search bar when typing quickly, and by looking at the execution time of
renderPDFs()in browser performance profiles. A Playwright test confirms there are no functional regressions.PR created automatically by Jules for task 6476172864110377918 started by @MrAlokTech
