Find nth element of Array using Javascript methods

Aniket Narvankar

I want to write a program to get nth element of given array in javascript. Using javascript methods. Also do not want to use slice. Please guide me on this.

I have tried this

const array = [1, 2, 3, 5]

function filterItems(array, index) {
return array[index];
}
console.log(filterItems(array, 0));

this will output 1. but how to do using javascript methods and without using slice

try {
  const array = [1, 2, 3, 5]

		function filterItems(array, index) {     
   
            return array[(array.length - (array.length- index))];
        }
        
        alert(filterItems(array, 3));
    }
catch(err) {
  document.getElementById("demo").innerHTML = err.message;
}

function nthElementFinder(a, n) {
    const result = [];
    let i = n - 1;
    while (i < a.length) {
        result.push(a[i]);
        i += n;
    }
    return result;
}

console.log(nthElementFinder([1, 2, 3,  5], 3));

Hello Aniket,

You can create function and use that function as below,

const getColumnCells = (cells, columnIndex) => {
  const columnCells = [];
  const delta = Math.floor(cells.length / columnIndex);

  for (let i = columnIndex; i < cells.length; i = i + delta) {
    columnCells.push(cells[i]);
  }
  console.log(columnCells);
  return columnCells;
};

const array = [1, 2, 3, 5]


getColumnCells(array, 2)

Above one will give Out put : 3
