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

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.

Frequently Asked Questions

What is the salary difference between TypeScript and JavaScript developers in 2026?

TypeScript developers command a 10-20% salary premium over pure JavaScript developers in most markets. Senior TS engineers earn EUR 70-95K in Germany, CHF 110-140K in Switzerland, USD 130-180K in the US, and EUR 30-50K in Turkey. However, the premium is shrinking as TypeScript adoption becomes the default for new projects. In practice, most senior JavaScript developers already know TypeScript, making the distinction less meaningful at the senior level.

Should you hire TypeScript or JavaScript developers?

For new projects, hire TypeScript developers — type safety reduces bugs by 15-25% in large codebases and dramatically improves maintainability. For legacy JavaScript codebases, hire strong JavaScript developers with TypeScript willingness. The migration cost is lower than rewriting. The most important signal is fundamentals: a great JavaScript developer who learns TypeScript in 2 weeks is better than a mediocre TypeScript developer who learned types but not architecture.

How large is the TypeScript developer talent pool compared to JavaScript?

JavaScript remains the larger talent pool — roughly 17 million developers globally versus approximately 10 million TypeScript developers. However, the gap is closing rapidly. In 2026, over 85% of new frontend and full-stack projects use TypeScript, and most senior JavaScript developers have TypeScript experience. The practical talent pool for TypeScript roles is much larger than the numbers suggest because strong JS developers can transition to TS within weeks.

How long does it take to hire a TypeScript or JavaScript developer?

Mid-level TypeScript developers can be hired in 25-40 days. Senior TypeScript engineers with framework expertise (React, Node.js, Next.js) take 35-55 days. The timeline is slightly shorter for JavaScript-only roles due to the larger talent pool. Sourcing across multiple markets (DACH, Turkey, UAE, US) significantly reduces time-to-hire by expanding the candidate pool beyond local competition.
