building on this: port 65536 is now a compile error. no runtime check, no recursion 🧱
ALT TypeScript code defining a Port type that accepts 1 to 65535, digit by digit, using template literal types. listen(3000) and listen(65535) compile, while listen(65536) and listen(0) are underlined in red as errors.
turns out TypeScript types can enforce a min and max string length too
ALT TypeScript code: a Username template literal type built from 3 required one-character placeholders and 5 optional ones, so only strings of 3 to 8 characters are allowed. "dan" and "danfry" compile; "df" (too short) and "danfrydev" (too long) are errors.

Built an open benchmark off the back of this: 5 typescript checkers, 3 real projects, raw output behind every result
Controlled numbers come in under my quick first run. tsc-ts is 4.5x faster than tsgo on type-fest at defaults, 3.4x with both at 10 threads.

another use: Ethereum addresses vs hashes (the case @MicahZoltu asked for in TypeScript issue #52243).
Address = exactly 40 hex chars, Hash = exactly 64, so mixing them up is a compile error. no brands, no runtime code.

Had a great time at #SvelteSummit and met some really amazing people, was also fortunate to get the chance to meet some of the folks who have had a major influence in my coding journey thus far - @Rich_Harris && @swyx - the future of webdev is looking bright! – at Stockholm, Sweden
