Custom Array Chunking via Iterator Protocol Implementation

export class ChunkedIterable {
  constructor(array, chunkSize) {
    this.array = array;
    this.chunkSize = chunkSize;
  }
 
  *[Symbol.iterator]() {
    for (let i = 0; i < this.array.length; i += this.chunkSize) {
      yield this.array.slice(i, i + this.chunkSize);
    }
  }
}
 
export function processBatch(dataset, size) {
  const batcher = new ChunkedIterable(dataset, size);
  return Array.from(batcher);
