Why this program matters

Without Express.js, your backend projects stagnate: 40% of junior devs lose 2 weeks on basic setups, exposing to security flaws (80% of breaches via unprotected routes, source OWASP).
Trained competitors deploy 3x faster, clients flee slow apps (churn rate +25%).
Unmanaged bugs cost 500€/incident in prod.
Invest 28h to avoid these pitfalls, master Express and multiply freelance opportunities tomorrow.
