The if-else statement

if-else statements are the most common way of making decisions in code. When stripped of all its syntax, the basic idea is, If my condition is met, execute this block of code; if it's not, execute this other block of code. Think of these statements as gates, or doors, with the conditions as their keys. To pass through, the key needs to be valid. Otherwise, entry will be denied and the code will be sent to the next possible gate. Let's take a look at the syntax for declaring one of these gates.
