useEffect(() => {}, []); Developer T-Shirt (React Edition — Dark Mode)

£25.00
Size

For devs who live in Dark Mode and fear the dependency array more than merge conflicts. This black unisex tee highlights the iconic React hook  useEffect(() => {}, []); — the “run once” pattern that powers countless components (and causes countless debates).

Minimal, modern, and instantly appreciated by anyone who's been caught in an infinite re-render loop. Soft, durable, and ideal for late-night coding sessions where you swear the effect used to work an hour ago.

  • 100% combed and ring-spun cotton (Heather colors contain polyester)
  • Fabric weight: 4.2 oz./yd.² (142 g/m²)
  • Pre-shrunk fabric
  • Side-seamed construction
  • Shoulder-to-shoulder taping
  • Blank product sourced from Nicaragua, Mexico, Honduras, or the US

Disclaimer: The fabric is slightly sheer and may appear subtly see-through under certain lighting conditions.

Printed on demand — stable, predictable, and never re-runs unexpectedly.

Part of the JavaScript collection, within Web & Frontend.

Available in Dark Mode and Light Mode.

Heads-up

Shipping costs vary by region, so it’s worth giving the delivery total at checkout a quick look before confirming your order. Some variants may show limited availability in certain locations—if fulfilment isn’t available in your region, our suppliers will try to ship globally from the nearest facility that can produce that specific item. When this happens, delivery costs may be higher than expected due to the increased distance.

We’re constantly reviewing suppliers and expanding fulfilment options, and new routes may open over time.
