Using std/crypto with x25519 crashes - How do i use node experimental modules instead?
@divy Thanks for the quick response in general! ❤️ I understand not spending time on helping to format issues, so i just went ahead and opened this the best i could - https://github.com/denoland/std/issues/6085

Using std/crypto with x25519 crashes - How do i use node experimental modules instead?
@divy Sorry to bother you but i dont want to be more intrusive then nessesary – so im opting to ask now instead of making mistakes later. Where do i open it?, std? - theres existing issues similar but seems outdated and stale. -https://github.com/denoland/std/issues/4224 and https://github.com/denoland/deno/issues/16145 but also super old. both still open.
