Answer 1

You can use the index (second parameter) in the array filter method like this:

let arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

// filter out all elements that are located at an even index in the array.

let x = arr.filter((element, index) => {
  return index % 2 === 0;
})

console.log(x) 
// [1, 3, 5, 7, 9]
