Anyone available to help me clean my code? Many thanks in advance!

   this.shoeName = shoeName; 
   this.productCode = productCode; 
   this.quantity = quantity; 
   this.itemValue = itemValue; 


     this.change = function (name, code, qty, value) {
      this.shoeName = name;
      this.productCode = code;
      this.quantity = qty;
      this.itemValue = value;

      console.log(`

      has been edited to:
      ${name} ${code} ${qty} ${value}

Here's a few suggestions. First, don't call console.log when using methods where you have it built-in:

// find "adidas"
shoeSearch(shoeStock, "adidas");                      // "console.log" is built-in
// try and find an item that doesnt exist
shoeSearch(shoeStock, "kicks");                       // "console.log" is built-in
// find highest item
highestItem(shoeStock);                               // "console.log" is built-in
// find lowest item
lowestItem(shoeStock);                                // "console.log" is built-in
// get any item description
console.log(sabat03.shoeDescription());
// edit an item
sabat01.change("nike", "nk020", 88, 175);             // "console.log" is built-in
// display product name in in ascending order
console.log(shoeStock.map(x => x.shoeName).sort());   // names only, sorted

I assume that last comment is meant to say "names" (plural). Is this from a course? You could include a link to the lesson page.

And the modern way of defining an object is with the "class" syntax:

class Shoes {                                                // "class" instead of "function"
  constructor(shoeName, productCode, quantity, itemValue) {  // constructor for initialization
    this.shoeName = shoeName;
    this.productCode = productCode;
    this.quantity = quantity;
    this.itemValue = itemValue;
  }

  change(name, code, qty, value) {                    // and methods have a simplified syntax
  // ...
