module HashDelegate

  # Like `delegate :foo, to: :bar` only for hashes instead
  # of objects. So these are the same:

  #   def foo
  #     bar[:foo]

  #   hash_delegate :foo, to: :bar

If you use server rendering, keep in mind that neither useLayoutEffect nor useEffect can run until the JavaScript is downloaded.

You might see a warning if you try to useLayoutEffect on the server. Here's two common ways to fix it.

Option 1: Convert to useEffect

If this effect isn't important for first render (i.e. if the UI still looks valid before it runs), then useEffect instead.

function MyComponent() {

}

// singleParent が欠けると => 複数の directory に属する file があらわれる

Implementation notes on react's scheduling model as of (shortly before) 16.8.0

While the public API intended for users to use is the scheduler package, the reconciler currently does not use scheduler's priority classes internally.

ReactFiberScheduler has its own internal "mini-scheduler" that uses the scheduler package indirectly for its deadline-capable scheduleCallback.

This is kind of a documentation of implementation details that I suppose will be gone by the end of the year, but what can you do.
