Building with TypeScript

TypeScript adds a type system to JavaScript. The compiler catches many mistakes, such as wrong argument types or possibly-undefined values, before the code runs, and editors use the types for autocompletion and safe renames.

What TypeScript Is Good At

  • Strict mode flags possible null and undefined access.
  • Editors offer autocompletion and cross-file rename refactoring.
  • Types can be shared between frontend and backend code.
  • Types document what each function accepts and returns.

Common Use Cases for TypeScript

  • Full-stack apps with shared API contracts
  • Business logic, financial tools, and data processing
  • Developer tools and SDKs

Frequently Asked Questions About TypeScript

Does TypeScript slow down an MVP?

Writing types has an upfront cost, but it usually pays back during refactoring, when the compiler points to every place a change breaks.
