Javascript split array to Chunks

In this tutorial, we will learn how to use JavaScript to split an array into smaller chunks or divide it into equal parts. This can be useful for processing large datasets, creating pagination, or displaying multiple items in a grid layout. There are different ways to achieve this, but one of the simplest and most popular methods is to use the slice() method of the array object.

The slice() method returns a new array containing a portion of the original array, without modifying it. By using a loop and a variable to keep track of the starting index, we can slice the array into chunks of any size we want. For example, if we want to split an array of 12 elements into 4 chunks, each containing 3 elements

Example 1 : Javascript Array Split to Chunks

This example has JavaScript code to split an array into chunks or divide it into equal parts. You can use it to edit your code as desired if you want.

Javascript Split Array of Objects by Property

  <script>
   window.addEventListener('DOMContentLoaded', (event) => {
    function chunkArray(array, chunkSize) {
     const chunkedArr = [];
     let index = 0;
     while (index < array.length) {
      chunkedArr.push(array.slice(index, index + chunkSize));
      index += chunkSize;
     }
     return chunkedArr;
    }
    const companyNames = ["Apple", "Microsoft", "Google", "Amazon", "Facebook", "Tesla", "Netflix", "Twitter", "Intel"];
    const chunkSize = 2;
    const chunkedCompanies = chunkArray(companyNames, chunkSize);
    const outputTableBody = document.querySelector('#output tbody');
    chunkedCompanies.forEach((chunk, index) => {
     const row = document.createElement('tr');
     const chunkNumberCell = document.createElement('td');
     const companyNamesCell = document.createElement('td');
     chunkNumberCell.textContent = `Chunk ${index + 1}`;
     companyNamesCell.textContent = chunk.join(', ');
     row.appendChild(chunkNumberCell);
     row.appendChild(companyNamesCell);
     outputTableBody.appendChild(row);
    });
   });
  </script>
