Microsoft's decision to rewrite TypeScript's compiler in Go promises significant performance improvements, although benefits will not be immediate.
In a surprising turn of events, Microsoft announced a complete reprogramming of TypeScript, a pivotal technology in modern web development. The primary motivation for this overhaul stems from the inherent limitations associated with TypeScript being written in its own language, resulting in suboptimal performance and lack of low-level optimizations such as direct memory access and native multi-threading. This led to Microsoft’s decision to rewrite the TypeScript compiler in Go, a programming language developed by Google. The anticipated optimizations are significant, boasting promises of tenfold improvements in compile times and overall performance, thus indicating a revolutionary advancement for developers relying on TypeScript for large-scale projects. Users are currently using TypeScript 5.8 and the awaited updates will not arrive until TypeScript 7, meaning potential benefits will take time to manifest as the transition takes place.

Claims:
Claim: TypeScript being written in TypeScript leads to performance limitations.
Evidence: The statement discusses how the TypeScript compiler's performance issues arise because it does not support low-level optimizations.
Counter evidence: Some argue that many programming languages are written in themselves and still manage to perform well, suggesting that the core issue might be design rather than language limitations.
Claim rating: 8 / 10
Claim: Switching to Go has resulted in the TypeScript compiler being ten times faster.
Evidence: The content claims that the compile time in VS Code dropped from 70 seconds to just 7 seconds, which demonstrates a significant speed enhancement.
Counter evidence: The actual performance may vary across different environments and projects, and not all developers may experience the same level of improvement.
Claim rating: 7 / 10
Claim: The new TypeScript compiler will not be available until TypeScript 7.
Evidence: The announcement mentions that although upgrades are worked on, they will not be available until a future release of TypeScript, specifically 7.
Counter evidence: Software release schedules can change rapidly and the timeline may face unexpected delays that have not been accounted for.
