title: Switch statement not working correctly in JavaScript
body: <p>I have the following piece of code. For some reason the case statement that I don't want to execute (second for Case '2') is getting executing in addition to the correct one (Case '4'). After reading online it appears most ppl were able to resolve similar issue by adding a "break" statement. However it isn't working for me. Please advise.Output below is from my Browser</p>
