Modify a data structure : Linked List - Independent Exercise

In this video tutorial, students are tasked with adding a new method called 'index of' to a linked list constructor function. This method will take a value and return all the indexes of that value in an array. An example is provided where the value 3 is found at positions zero and two in a linked list. Students are encouraged to take their time and refer to previously created methods for ideas. The next video will review this exercise and provide a solution, so students are advised to attempt the problem before proceeding.

What should the 'index of' method return if the value 3 is found at positions zero and two?

What should you do if you need help with the 'index of' method implementation?
