Intro to DatasetSlice

DatasetSlice allows you to lazily arrange your Dataset’s data.

DatasetSlice is faster when it comes to shuffling than normal Arrays.

Creating DatasetSlice

import toynn from 'toynn';

const myDataset = await toynn.Dataset.from('./myData.csv');

console.log(myDataset.toArray().map((e) => e.flatten())); // => [[1,2],[3,4],[5,6]]
const myDatasetSlice = new toynn.DatasetSlice(myDataset, [1, 0, 2]);

console.log(myDatasetSlice.toArray().map((e) => e.flatten())); // => [[3,4],[1,2],[5,6]]

Note: All methods of Dataset are supported by DatasetSlice and works the same way.
