What steps will reproduce the bug?

f.js contains only console.log('hello')

node --watch f.js
hello
Completed running 'f.js'

Change f.js to console.log('hello world')

Restarting 'f.js'
hello world
Completed running 'f.js'

Change f.js again, e.g. console.log('this change will not restart watcher')
No change in the watch output.

(I'm changing the file outside of the debounce/throttle period)

How often does it reproduce? Is there a required condition?

It happens every time.

What is the expected behavior? Why is that the expected behavior?

I would expect that --watch would restart after every write to f.js, not just after the first change made to the file.

What do you see instead?

--watch only seems to restart after making the first change to the file.

まず node --watch f.js で問題を再現します。debounce/throttle の期間外にファイルを複数回変更してください。--watch のエントリポイントとその再起動処理を追跡します。完了の条件は、f.js への後続の書き込みがすべてプロセスを再起動し、報告された環境で動作が検証されることです。
