Restricting number of user selections from Dropdown listbox multi option in JavaScript

We can select more than one option from a drop down list box when we use the option multi .
User can press Ctrl key and go for multiple selection from the given options.

Here we can restrict the number of options selected by user by using JavaScript. Here we have listed multiple colour options for the user to select. Once the selection reaches 4 options , one alert message will be displayed asking the user to select only 3 options and the last selected option will be deselected.
Using checkboxes we can limit the number of selections
