split large array into chunks code example

Example 1: 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); //split into chunks of two

Example 2: array chunk javascript

let input = [1,2,3,4,5,6,7,8,9];
let chunked = []
let size = 2;

for (let i = 0;  i < input.length; i += size) {
  chunked.push(input.slice(i, i + size))
}
console.log(chunked)

Example 3: array chunk javascript

let input = [1,2,3,4,5,6,7,8];
let chunked = []
let size = 2;

Array.from({length: Math.ceil(input.length / size)}, (val, i) => {
  chunked.push(input.slice(i * size, i * size + size))
})

console.log(chunked);

Example 4: split array into chunks javascript

Array.prototype.chunk = function(size) {
    let result = [];
    
    while(this.length) {
        result.push(this.splice(0, size));
    }
        
    return result;
}

const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9];
console.log(arr.chunk(2));

Example 5: 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));
  };
}

Example 6: array chunk javascript

const tips_vectorDistance = (x, y) =>
  Math.sqrt(x.reduce((acc, val, i) => acc + Math.pow(val - y[i], 2), 0));
console.log(tips_vectorDistance([15, 0, 5], [30, 0, 20]));
