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

var arrayMap = array
  .slice(0, 4) //this remove bettwen array elements
  // or uou can use .slice(1) it will remove everything that is smaller than the array element

  .map((x) => array[x])
  .join(", ")

console.log(arrayMap) //will return 2, 3, 4, 5

// i hope it helped
