How to use Array.from() and Array.splice() In Javascript
This method involves creating a new array from the original array using Array.from() and then repeatedly removing elements from it using splice() to form chunks.
Example: In this example The chunkArray function splits an array into chunks of a specified size. It creates a copy of the original array and iteratively extracts portions based on the chunk size until the array is empty.
function chunkArray(array, chunkSize) {
const chunks = [];
const copyArray = Array.from(array); // Create a copy of the original array
while (copyArray.length > 0) {
chunks.push(copyArray.splice(0, chunkSize));
}
return chunks;
}
// Example usage:
const arr = [1, 2, 3, 4, 5, 6, 'a', 'b', 'c', 'd'];
const chunkSize = 3;
const chunks = chunkArray(arr, chunkSize);
console.log(chunks);
Output
[ [ 1, 2, 3 ], [ 4, 5, 6 ], [ 'a', 'b', 'c' ], [ 'd' ] ]
Split an array into chunks in JavaScript
Splitting an array into chunks in JavaScript involves dividing the array into smaller arrays of a specified size. This process is useful for managing large datasets more efficiently or for processing data in smaller, more manageable portions within the application.
Methods to split the array into chunks:
