Could anyone help me with this question?

****JAVA SCRIPT****

1. Finish the simulation program of the Monty Hall paradox that was discussed in class. Your program should ask the user if she wants to always switch or never switch, and then silently simulate the game 10,000 times given this decision. Dont repeatedly ask the user for her decision on each trial! Dont print out any debugging text! Print out only the overall fraction of times the player wins the fabulous grand prize.

This is what I have for the code so far! ****JAVA SCRIPT****
