• _dtrace.ts
• _errors_test.ts, _errors.ts
• _fixed_queue.ts refactor(node): move _fixed_queue.ts to node/internal #2064
• _idna.ts
• _options.ts refactor(node): move _options.ts to node/internal #2065

• _timers.ts feat(node): add Timeout class #1699
• _util/_debuglog,ts -> internal/util/debuglog.ts

@getspooky Thank you for creating this issue!

Right. We should keep the file structure as close as possible to Node.js structure. The above change make sense to me.

BTW node/_core.js is something we invented on our own. Maybe we should keep it somewhere else?

Also deno_std/node/_buffer.js seems corresponding to node/lib/buffer.js. So let's just rename it to deno_std/node/buffer.js in this case.

Please carefully compare node.js lib/ directory and deno_std node/ directory before starting working on each item

@kt3k thanks for feedback, i will start working on it

Also _timers will conflicts with #1699. Please avoid it at first.

I updated the description, and crossed out some items (_core.ts _events.js _next_tick.ts _utils.ts) which don't seem existing in internal/

@kt3k, I'll do _readline.mjs. Is there any issue in essentially merging the .mjs and .d.ts files into a .ts file? I gather that .mjs is separated to make following the node version easier to follow.

[kt3k]

@iuioiua I think there's no such issue. Do you think we should merge .mjs and .d.ts into .ts?

Looks these are all done now. Thanks for your efforts!
