## Summary This PR adds early return to the `diff` function. We don't need to go through all the entries of `nextProps`, process and deep-diff the values if `nextProps` is the same object as `prevProps`. Roughly 6% of all `diffProperties` calls can be skipped. ## How did you test this change? RNTester.

// population running in either mode, we should run our tests that way, too,

// with the __VARIANT__ set to `true`, and once set to `false`.

// TODO: __VARIANT__ isn't supported for React Native flags yet. You can set the

|
// flag here but it won't be set to `true` in any of our test runs. Need to
|
|
// add a test configuration for React Native.
