Shuffle multiple arrays randomly and keep them synchnorized.
On the command line:
npm install synchronized-array-shuffle
In your file:
import synchronizedShuffle from 'synchronized-array-shuffle';
const A = ['a', 'b', 'c'];
const B = ['1', '2', '3'];
const [ A_shuffled, B_shuffled ] = synchronizedShuffle([ A, B ]);
// possible output
console.log(A_shuffled);
// ['c', 'a', 'b']
console.log(B_shuffled);
// ['3', '1', '2']
