Chunk an Array into Size N

let arr = [1,2,3,4,5]
let n = 3

function chunkArray(arr, n){
    let res=[]
    for(let i=0;i<arr.length;i+=n){
        res.push(arr.slice(i, i+n))
    }
    return res;
}
const d = chunkArray(arr, n)
console.log(d)

Hi Everyone,
This was one of the javascript question that was asked during an interview - Batch api call

const urls = [
  'https://jsonplaceholder.typicode.com/posts/1',
  'https://jsonplaceholder.typicode.com/posts/2',
  'https://jsonplaceholder.typicode.com/posts/3',
  'https://jsonplaceholder.typicode.com/posts/4',
  'https://jsonplaceholder.typicode.com/posts/5',
  'https://jsonplaceholder.typicode.com/posts/6',
  'https://jsonplaceholder.typicode.com/posts/7',
  'https://jsonplaceholder.typicode.com/posts/8',
  'https://jsonplaceholder.typicode.com/posts/9',
  'https://jsonplaceholder.typicode.com/posts/10'
];


async function limitAPICalls(urls, limit = 3) {
  for (let i = 0; i < urls.length; i += limit) {
    const batch = urls.slice(i, i + limit);

    const responses = await Promise.all(
      batch.map(url => fetch(url).then(res => res.json()))
    );

    responses.forEach((res, index) => {
      console.log(`Response ${i + index + 1}:`, res);
    });
  }
}
const limitApis = limitAPICalls(urls)
