Your code so far


const s = [5, 7, 2];
function editInPlace() {
  "use strict";
  // change code below this line

  // s = [2, 5, 7]; <- this is invalid

  // change code above this line
}

to change the values of an array you must use square bracket notation.
For eg.

const arr = [‘hello’, ‘there’];

arr[0] = ‘goodbye’;

the last line will change ‘hello’ to ‘goodbye’

const s = [5, 7, 2];
function editInPlace() {
  "use strict";
  // change code below this line
  let x = s.pop();
  s.unshift(x);
  // s = [2, 5, 7]; <- this is invalid

  // change code above this line
}
editInPlace();
