How can I use JavaScript to split an array into chunks of a specific size?

Hey, having worked with JavaScript for a good few years, I’ve often needed to split big arrays into smaller chunks manually. One of the easiest and clearest ways is by using a basic for loop. Here’s how you can do it:

function splitArrayIntoChunks(arr, chunkSize) {
    let result = [];
    for (let i = 0; i < arr.length; i += chunkSize) {
        result.push(arr.slice(i, i + chunkSize));
    }
    return result;
}

const arr = ["Element 1", "Element 2", "Element 3", "Element 4", "Element 5", "Element 6"];
console.log(splitArrayIntoChunks(arr, 2));

This method is super straightforward - you loop over the array, slicing it into parts of your desired size. If you’re just starting with the javascript split array into chunks concept, this is a great first approach. Plus, you get total control over the process if you need to tweak it later.
