Make the web (development) faster.
swc is a super-fast typescript / javascript compiler written in rust.
Check out the documentation in the website.
Please see comparison with babel.
The lower bound of the speedup compared to babel is 18. The benchmarks were run on Macbook pro, dual core, 2.3GHz Intel Core i5, 16 GB ram
