How to use JavaScript for my complex validation requirements?

I am trying to limit the number of checkboxes based on the radio button choice. I have 4 radio buttons and 12 checkboxes and I want the user to be able to pick:

a minimum of 2 checkboxes and a maximum of 4 checkboxes when he selects the first radio button,

a minimum of 5 checkboxes and a maximum of 6 checkboxes when he selects the second radio button,

a minimum of 7 checkboxes and a maximum of 8 checkboxes when he selects the third radio button,

a minimum of 10 checkboxes and a maximum of 12 checkboxes when he selects the fourth radio button.
