If-Else
If/else statements are one of the most fundamental tools in writing scripts. These statements check to see if a statement is true, if it is true it will perform a set of actions. If it is not true it will skip those actions and continue to the next statement until a statement is true or it runs out of statements to check.
Example 1 - Always true
Example 2 - Always false
Example 3 - Sometimes true
Example 4 - If, else-if
Example 3 - If, else-if, else
