Break up an array into chunks of a given size.

chunk.js

module.exports = (data, size = 10) => {
    let chunk = [];
    
    return data.reduce((chunks, item, index) => {
        chunk.push(item);
        
        if (chunk.length >= size || index === data.length - 1) {
            chunks.push(chunk);
            chunk = [];
        }
        
        return chunks;
    }, []);
};
