Modern JavaScript from the Beginning - Second Edition - Array Chunking

The video tutorial covers array chunking in JavaScript, starting with setting up a project and using Node.js's assertion library with Jest for testing. It explains how to write tests for an array chunking function, implement the function using JavaScript, and run tests to ensure it works correctly. The tutorial also highlights debugging techniques and emphasizes the flexibility of using different methods for testing.

What should the output of the chunk function be when given an array of [1, 2, 3, 4] and a chunk size of 2?

How does the chunk function handle cases where the array length is not a multiple of the chunk size?

What is the final step after writing the chunk function in the testing process?
