An interview with Anders Hejlsberg: his origin story; how he created TypeScript, C#, Delphi and Turbo Pascal; open source; his daily workflow; his thoughts on AI, Solidity, Rust, and more.
Create React App 4.0 is a major release with several new features, including support for Fast Refresh

Anders Hejlsberg has been working on interesting new type system capabilities: template string types as well as mapped type as clauses. Both features are slated for the upcoming TypeScript 4.1 release.
TypeScript 3.3 is a smaller release than usual and contains no breaking changes, so it should be easy to upgrade if you’re on an older version. Let’s explore what’s new in 3.3!

Why We Chose Typescript?
requirements:
- Must have types.
- Must have good tooling already.
- Powers major production apps.
- Our devs should be able to onboard fairly quickly.
- Should work on both the client and the server.
- Good library support.
TypeScript uses the typeof keyword for capturing anonymous types. Despite the same name, it is very different from JavaScript's typeof operator — in fact, the two can only appear in mutually exlusive places.
TypeScript has some "interesting" limitations when it comes to overloading functions. But it also offers you some options when you need more flexibility in declaring functions, including both optional parameters and infinite parameter lists.
These include automating tasks, open-sourcing our code, adding package manager support, using a build server to automatically build (and test) our software, supporting TypeScript and adding our library to a CDN.
