Without TypeScript, 70% of JavaScript bugs stem from typing errors, wasting 40% of development time on endless debugging, as shown by Stack Overflow studies.
Imagine redeploying a production app due to an unexpected 'undefined', losing hours on poorly typed props in React, or seeing your teams slowed by conflicting merges.
With untyped JS projects, maintenance costs explode by 25% according to Gartner.

Invest 21 hours to eliminate these pitfalls and boost your productivity by 30%.
