Day 3 Questions

1. What is a conditional statement? Give three examples.

A conditional statement: is one where a decision must be made.

• e.g.: Is it too loud outside? If yes, close the window. If no, keep the window open.
• e.g. 2: Are you allergic to nuts? If yes, you can't eat the cookie. If no, you can eat the cookie.
• e.g. 3: Is it your bedtime? If yes, go to sleep. If no, you can play.

1. Why might you want to use an if-statement?

You might want to use an if-statement when you want to give a script two or more options of what could happen next. What happens next is determined by what condition is met.

    // code to execute for all other conditions
}
