/* There are 4 types of loops:
1) while - loops through a block of code as long as the specified condition is true
2) do...while - loops through a block of code once, and then repeats the loop as long as the specified condition is true
3) for - loops through a block of code a specified number of times
4) foreach - loops through a block of code for each element in an array

#While loop syntax

#While loop example
