Example 1: react split array into chunks
const chunkSize = 10;
const arr = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17];
const groups = arr.map((e, i) => {
return i % chunkSize === 0 ? arr.slice(i, i + chunkSize) : null;
}).filter(e => { return e; });
console.log({arr, groups})
Example 2: javascript split array into chuncks of
function splitArrayIntoChunksOfLen(arr, len) {
var chunks = [], i = 0, n = arr.length;
while (i < n) {
chunks.push(arr.slice(i, i += len));
}
return chunks;
}
var alphabet=['a','b','c','d','e','f'];
var alphabetPairs=splitArrayIntoChunksOfLen(alphabet,2);
Example 3: js split array into smaller arrays
Array.prototype.chunk = function(n) {
if (!this.length) {
return [];
}
return [this.slice(0, n)].concat(this.slice(n).chunk(n));
};
console.log([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15].chunk(5));
