One of the key features of all good programming languages is the ability to control the order in which actions are performed.  For instance, you may want to run one piece of code if the user has selected a checkbox, but run a different piece of code if they haven't selected it. Or, you may want to run the same piece of code 10 times .  Can you guide me that how can i write code to make decisions in JavaScript ? Thanks advanced for any guidace .
