How to limit the output of data from an array in JavaScript?

There is an array: [{},{},{},{},{},{}, .... more than 500 indices];
I want to make sure that initially I get them 50 pieces, the rest only if necessary, again 50 each and not all at once.

Answer 1

const arr = [...]
let part = 1; // или в стейте

const getAnother50 = () => {
  return arr.slice((part - 1) * 50, part * 50)
}

Increase part if necessary.

Answer 2

You can make YOUR iterator, which will produce 50 elements.
