Summary: This PR removes the need for having the `providesModule` tags in all the modules in the repository. It configures Flow, Jest and Metro to get the module names from the filenames (`Libraries/Animated/src/nodes/AnimatedInterpolation.js` => `AnimatedInterpolation`) * Checked the Flow configuration by running flow on the project root (no errors): ``` yarn flow ``` * Checked the Jest configuration by running the tests with a clean cache: ``` yarn jest --clearCache && yarn test ``` * Checked the Metro configuration by starting the server with a clean cache and requesting some bundles: ``` yarn run start --reset-cache curl 'localhost:8081/IntegrationTests/AccessibilityManagerTest.bundle?platform=android' curl 'localhost:8081/Libraries/Alert/Alert.bundle?platform=ios' ``` [INTERNAL] [FEATURE] [All] - Removed providesModule from all modules and configured tools.

/**
|
|
* Useful method to split an array into groups of the same number of elements.
|
|
* You can use it to generate grids, rows, pages...
|
|
*
|
|
* If the input length is not a multiple of the count, it'll fill the last
|
|
* array with null so you can display a placeholder.
|
|
*
|
|
* Example:
|
|
* groupByEveryN([1, 2, 3, 4, 5], 3)
|
|
* => [[1, 2, 3], [4, 5, null]]
|
|
*
|
|
* groupByEveryN([1, 2, 3], 2).map(elems => {
|
|
* return <Row>{elems.map(elem => <Elem>{elem}</Elem>)}</Row>;
|

* })
