A modern look and fully mobile-friendly design — this is how we created the new version of ads.allegro.pl.
Unfortunately, several hundred tests did not protect us from errors.
The last straw was when a simple but very annoying problem appeared in production.
We decided to start a revolution. We considered Flow, but ended up adopting TypeScript
for Allegro Ads.
