Find the Minimum and Maximum doesn't pass the test

Tell us what’s happening:
When I’m emulating the work of my algorithm outside of freecodecamp, it works. But it doesn’t pass the test on the website page.

Your code so far


var displayTree = tree => console.log(JSON.stringify(tree, null, 2));
function Node(value) {
this.value = value;
this.left = null;
this.right = null;
}
function BinarySearchTree() {
this.root = null;
// change code below this line
this.findMin = function(){
  var minValue
  if (this.root == null) {
    return null
  }
  node = this.root
  minValue = node.value
  while (node.left != null) {
    node = node.left
    minValue = node.value
  }
  return minValue
}
this.findMax = function(){
  var maxValue
  if (this.root == null) {
    return null
  }
  node = this.root
  maxValue = node.value
  while (node.right != null) {
    node = node.right
    maxValue = node.value
  }
  return maxValue
}
// change code above this line
}

it may be you have some undeclared variables or stuff like that
in the editor in which this algorithm works add 'use strict' (quotes included) on the first line, and see what errors pop out

Yes, it helped. It was exactly it. Thank you.

the freecodecamp editor runs in strict mode, you will know for next time!
