TypeScript is going Go: Why it’s the pragmatic choice
- The article discusses the porting of TypeScript to Go known as 'TypeScript 7' and reflects on the thoughts of two individuals in the TypeScript community.
- The decision for the Go port was driven by the need for performance improvements that other tools in the JavaScript ecosystem were demonstrating.
- The port to Go focused on enhancing the speed of the type checker, compiler, and language services, leading to faster feedback and builds for developers.
- TypeScript’s compiler will no longer be written in TypeScript but in Go, marking a shift in the development process.
- Concerns about reduced TypeScript usage by the team and its impact on community feedback and TypeScript’s influence on JavaScript evolution are addressed in the article.
- The article also explores the implications on interacting with TypeScript via its CLI, JavaScript API, language server, and other tools within the ecosystem.
- Tools like ts-loader and ts-blank-space may need adjustments due to internal API changes, while TypeScript-eslint is expected to benefit from the performance enhancements.
- The choice of Go over other languages like C# or Rust for the TypeScript port is attributed to Go's pragmatic nature and its alignment with TypeScript's ethos.
- The article also delves into the implications of JavaScript's performance for implementing a type checker and the speed gains achieved through the TypeScript to Go port.
- In conclusion, the article emphasizes the importance of performance in the ecosystem and expresses optimism about the TypeScript team's approach towards the migration.
