Works for <link rel="stylesheet"> too.

Sometimes unnecessarily.

Understanding React Compiler | Tony Alicea Cache all the things. How React Compiler works under-the-hood.

Not sure how I feel about React 19’s new Compiler… auto-optimizing sounds cool, but I worry it’ll hide performance issues instead of teaching devs to write better code. 🤔

I Pray everyday that the truth is exposed in a way that everyone can see. It's so upsetting that so many of my family and friends don't believe in vaccine injuries when I have been FIGHTING for my life since 2 weeks after my second Pfizer covid bioweapon (it's not a vaccine). Is it cognitive dissonance or is it they don't care? Either way, my God is bigger and greater then all of this and he has gotten me this far. #GodsPlan #Godisgood #prayerworks #facts #injured #react19 #COVID19 #mastcellactivationsyndrome #portsurgery #venogram #PfizerLiedPeopleDied #covid_19 #LaraTrump #joerogan #TuckerCarlson #FoxNews #iwantmylifeback #help #faithoverfear #faith
