typed superset of JavaScript

TypeScript in 30 seconds

TypeScript is an open-source language developed by Microsoft that adds static types to JavaScript and compiles to plain JavaScript, catching a class of errors before code ever runs.

It has become the default for new front-end and Node.js projects because types double as documentation and make large refactors survivable.

What a TypeScript developer actually works on

  • Typed front ends and shared types between client and server
  • Library and SDK work where the public type surface is the product
  • Incremental migration of an existing JavaScript codebase

What to check before you hire a TypeScript developer

  • Generics and utility types used to model real domain rules, not decoration
  • Strict mode discipline and their position on the any escape hatch
  • Experience migrating a JavaScript codebase without stopping delivery

Is TypeScript the right call?

TypeScript is the professional default for JavaScript work. The signal to look for is judgement about how much type complexity a team can actually maintain.

Frequently asked questions

Is a TypeScript developer role different from a JavaScript role?

In practice it signals codebase maturity: strict typing, review culture, and API discipline. The posting attracts engineers who prefer that environment, which is usually the point.

What do TypeScript developers earn?

US base salaries typically run $100,000 to $172,000 depending on stack and seniority, essentially matching senior JavaScript rates with a modest premium for advanced type skills.

How advanced should our type-skill requirements be?

Require fluency with generics and discriminated unions; treat exotic conditional-type wizardry as neutral or even a caution sign. Maintainable types beat impressive ones.

How do we assess type design skill in interviews?

Give a small domain and ask the candidate to model it in types: an order lifecycle, a permission system. Their choices reveal design judgment no quiz can.
