1:1 line number mapping
Is there a way to have line numbers in typescript be the same line numbers as javascript? For example, if there's a statement on line 17 in the TS source, SWC would put it on line 17 in the generated JS
I'm using the Rust API

See https://rustdoc.swc.rs/swc_fast_ts_strip/fn.operate.html and related examples in the main repository
operate in swc_fast_ts_strip - Rust

great, thanks! I'm not seeing much in the docs about this, should I expect to be able to achieve 1:1 line number mapping?
The idea behind
https://bloomberg.github.io/ts-blank-space/
swc_ts_fast_strip originated from ts-blank-space. This approach introduces specific constraints on TypeScript that make it possible to safely strip its type annotations. If you're curious about the concept, you might want to check out the original explanation:https://bloomberg.github.io/ts-blank-space/
ts-blank-space
A small, fast, pure JavaScript type-stripper that uses the official TypeScript parser.
