    Cant seem to figure out how to do the following

    Id like the following program to be able to:
    - Deselect numbers
    - Allow user to guess the same set of numbers, multiple times
    - Show the history of guesses
    - An alert for good guess.

    To toggle the button, add and remove a class using classList.add() and classList.remove(). You'll use classList.contains() to determine whether the to add or remove the class. That'll toggle the styles. You can use array.indexOf() to find a number in the array, and array.splice() to remove it.

    Not entirely sure what your second point is asking for.

    Showing the history of guesses can be done by storing them in a multidimensional array. You'll use array.push() to add an array to the last position of the parent array. [[1, 3, 5], [5, 6, 7]] <= new array gets "pushed" into the bottom. Then, use a nested for loop to output.
