The Release Candidate of TypeScript 4.0 was announced today.

There are no larger breaking changes from TypeScript 3.9. Here are few features I was waiting for:

  • Short-Circuiting Assignment Operations
  • Unknown on catch Clause Bindings
  • Custom JSX Factories
  • Convert to Optional Chaining

Here is the complete list >>
