We should always refine the type of fiber before checking the effect
flag, because the fiber tag is more specific.
Now we have a single switch statement for all mutation effects.
The fiber tag is more specific than the effect flag, so we should always
refine the type of work first, to minimize redundant checks.
In the next step I'll move all other other flag checks in this function
into the same switch statement.
There's not really any reason these should be separate functions. The
factoring has gotten sloppy and redundant because there's similar logic
in both places, which is more obvious now that they're combined.
Next I'll start combining the redundant branches.
commitWork is forked into a separate implementation for mutation mode
(DOM) and persistent mode (React Native). But unlike when it was first
introduced, there's more overlap than differences between the forks,
mainly because we've added new types of fibers. So this joins the two
forks and adds more local branches where the behavior actually
diverges: host nodes, host containers, and portals.
I'm about to refactor part of the commit phase to use recursion instead
of iteration. As part of that change, we will no longer assign the
`return` pointer when traversing into a subtree. So I'm disabling
the internal warning that fires if the return pointer is not consistent
with the parent during the commit phase.
I had originally added this warning to help prevent mistakes when
traversing the tree iteratively, but since we're intentionally switching
to recursion instead, we don't need it.
The problem in scripts\babel\transform-object-assign.js is that file path separator has '/' and '\' between Linux, MacOS and Windows, which causes yarn build error. See https://github.com/facebook/react/issues/24103
This PR moves the code for transition tracing in the mutation phase that adds transitions to the pending callbacks object (to be called sometime later after paint) from the mutation to the passive phase.
Things to think about:
Passive effects can be flushed before or after paint. How do we make sure that we get the correct end time for the interaction?
* Switched RulesOfHooks.js to use BigInt. Added test and updated .eslintrc.js to use es2020.
* Added BigInt as readonly global in eslintrc.cjs.js and eslintrc.cjs2015.js
* Added comment to RulesOfHooks.js that gets rid of BigInt eslint error
* Got rid of changes in .eslintrc.js and yarn.lock
* Move global down

This type isn't exported so it's technically not public.
This object mimics a ReadableStream.
Currently this is safe to destructure and call separately but I'm not sure
that's even guaranteed. It should probably be treated as a class in docs.
