Usage

Here is an example of how to use the Utilities Library:

import { chunkArray } from "@mkholt/utilities";

// Example usage
const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9]
 for (const chunk of chunkArray(arr, 3)) {
    console.log(chunk)
 }
 // [1, 2, 3]
 // [4, 5, 6]
 // [7, 8, 9]

 const arr2 = [1, 2, 3, 1, 2, 3, 4, 5]
 const unique = arr2.filter(isUnique)
 // unique = [1, 2, 3, 4, 5]
