TypeScript to Go 10X Faster !!!

According to TypeScript’s official announcement, they are fully rewriting TypeScript in Go, achieving a 10x speedup.

To get more info about the announcement, follow this Official Typescript Blog Link .

Here’s the some insights I get to know after taking time overviewing the annoucements and reading the blogs which have covered the breaking changes.

Will this impact me?

TypeScript is being rewritten in Go, which will make everything much faster for developers. Here’s how it helps:

• Faster Coding Experience – Your code editor (like VS Code) will respond 10x faster when showing errors, suggestions, and navigating through code. This is especially helpful for large projects.

• Faster Compilation – The TypeScript compiler (tsc) will work 10x faster, making your projects build quickly. This also means faster CI/CD pipelines, so deploying apps will take less time.

Simply put, everything you do with TypeScript will become way smoother and quicker which means “ IT IMPROVE DX FOR EVERY TYPESCRIPT DEVELOPERS.”

Need to update my code?

The answer is NO. The code remains the same.

Why Not Rust?

Well, the typescript team has put the reason for choosing Go behind all others in its github discussion. Here’s the link: https://github.com/microsoft/typescript-go/discussions/411 .

Go was the best choice mainly because it is very similar to JavaScript in structure. Its coding style is a lot like TypeScript’s current setup, making the transition smoother.

Why not make the JavaScript code faster instead?

I found the topic covered watching the videos in youtube, sharing their views on javascript and typescript. To simply put this on the table, JavaScript runs on a single thread, meaning it can only handle one task at a time. The reason JavaScript itself wasn't optimized for speed. While upcoming features like Shared Structs may improve this in the future, they aren’t fully developed yet. On the other hand, languages like Go and Rust have built-in multi-threading support, allowing them to use multiple CPU cores to process tasks simultaneously. This parallel processing makes them much faster than JavaScript, which is why TypeScript is being rewritten in Go instead of trying to speed up the existing JavaScript code.
