Week 38 - 2020

The weeknote for 9/14 - 9/20.

OSS

denoland/deno

🦕 Deno is a new JavaScript and TypeScript runtime

• My contributions

  https://github.com/denoland/deno/pull/7507

  Added alert, confirm, and prompt function from the web standards. It uses only JavaScript for the implementation. So the performance is not so good. It can be improved by the special op for reading a single line, but that seemed too much for this single purpose. So I avoided adding such op.

  I expected some negative arguments against introducing these features because in the original issue it had some negative arguments. However it only got positive feedbacks at the time of writing.

  My reasoning behind this addition is that it's little too complex to read a single line from stdin in Deno, just like Node.js. It requires TextDecoder, Uint8Array, while-loop, and optionally Promise. That's not a big deal for the advanced users, but actually a nightmare for beginners of Deno, beginners of JavaScript, or beginners of Programming. A task like reading a single line from stdin is important for learning the runtime to do basic excercises in the first chapters, but current Deno's API sets have a big bar for it. Reading a single line is very difficult (for beginners)! I'd like to remove that bar from Deno.

  I first tried to add something like Deno.readLineSync, but after thinking a while I realized it was actually prompt of web standards. So I came up with this PR.

Tech

• A new service called zenn.dev has been launched this week and it got huge popularity in Japanese tech scene. Maybe it'll be a big service in a while.
