chunk with javascript code example
Example 1: javascript array split chunk
const chunk = (arr, size) => arr.reduce((acc, e, i) => (i % size ? acc[acc.length - 1].push(e) : acc.push([e]), acc), []);
chunk([1, 2, 3, 4, 5, 6, 7, 8], 3);
chunk([1, 2, 3, 4, 5, 6, 7, 8], 4);
Example 2: chunk an array
function __chunk(array, size) {
let chunkArray = [];
return function _chunk(chunk = array) {
if (chunk.length < size) {
return chunkArray.push(chunk) && chunkArray;
}
return chunkArray.push(chunk.slice(0, size)) && _chunk(chunk.slice(size));
};
}
