Should I Use TypeScript?

Typed superset of JavaScript

Go for it
Score
9/10

Yes — the productivity and safety gains compound over time.

▲ Pros
  • +Catches entire categories of bugs before runtime — null checks, type mismatches, missing properties
  • +IDE autocomplete and refactoring become dramatically more reliable
  • +Self-documenting code — types serve as living documentation
  • +Industry standard — most new JS projects are TypeScript by default
▼ Cons
  • Initial setup and configuration can be frustrating (tsconfig complexity)
  • Type gymnastics for complex patterns can waste hours
  • Build step adds complexity to the toolchain
  • Over-typing is a real problem — not everything needs a type

Tech LeadGo for it

We mandate TypeScript for all new code. The 10% slower writing speed is offset by 50% fewer production bugs.
