TypeScript vs JavaScript Developers: Who Should You Hire in 2026?
TypeScript has gone from “nice to have” to “required” at most serious companies. But does that mean JavaScript developers are obsolete? Here is what the data says — and how it affects your hiring strategy.
The Market in Numbers
TypeScript
- 78% of new projects on GitHub use TS
- Required in 65% of DACH job postings
- 5-15% salary premium over JS-only
- Default for: Next.js, Angular, enterprise
JavaScript
- Still the runtime — TS compiles to JS
- Dominant in legacy codebases
- Larger candidate pool (lower barrier)
- Default for: rapid prototyping, small teams
Salary Comparison (Senior, 2026)
When to Hire TypeScript Developers
- ✓Building a product that will scale (50K+ lines of code)
- ✓Team larger than 5 developers
- ✓Enterprise clients who expect type safety
- ✓API-heavy architecture (TS + tRPC/GraphQL)
- ✓Already using Angular or Next.js
When JavaScript Is Still the Right Call
- ✓Prototyping / MVP stage (speed over safety)
- ✓Small team (1-3 devs) with full-stack needs
- ✓Existing JS codebase without migration budget
- ✓Node.js scripting and automation
The Practical Truth
Most senior JavaScript developers already know TypeScript. The transition takes weeks, not months. If a candidate has 5+ years of JS experience, strong fundamentals, and has worked with typed languages before, they can contribute to a TS codebase quickly.
Our recommendation: hire for fundamentals and problem-solving ability, not for TypeScript-on-the-resume. A great JS developer who learns TS in 2 weeks is better than a mediocre TS developer who learned types but not architecture.
