Ways to split an array into chunks
1. Using while loop
Let’s use the following code to split an array into chunks using the while loop.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | const list = ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5', 'Item 6', 'Item 7', 'Item 8', 'Item 9', 'Item 10']; const chunkSize = 3; const chunkList = []; while (list.length) { chunkList.push(list.splice(0, chunkSize)); } console.log(chunkList); // [ // ['Item 1', 'Item 2', 'Item 3'], // ['Item 4', 'Item 5', 'Item 6'], // ['Item 7', 'Item 8', 'Item 9'], // ['Item 10'] // ]; |
2. Using lodash function
Now, we will show you another option to get the chunks using the lodash chunks method.
1 2 3 4 5 6 7 8 9 10 | const list = ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5', 'Item 6', 'Item 7', 'Item 8', 'Item 9', 'Item 10']; const chunkSize = 3; const chunkList = _.chunk(list, chunkSize); console.log(chunkList); // [ // ['Item 1', 'Item 2', 'Item 3'], // ['Item 4', 'Item 5', 'Item 6'], // ['Item 7', 'Item 8', 'Item 9'], // ['Item 10'] // ]; |
