+== is used to check for relative equality, whereas === is used to check for strict equality.
+
+In other words, the string '2' will evalutae to true when compared to the integer data type for 2 for equality.
+
+=== will check to see if the contents AND data type are the same, so since a string and an integer aren't the same, it would
+evaluate to false.
+
+TLDR:
+
+'2' == 2 will evaluate to True, since the contents are the same
+
+'2' === 2 will evaluate to False, since the data types are different.

+A while loop will only begin to execute if the conditional statement in the while statement is true.
+
+A do while loop will always execute its contents at least once, regardless of whether the conditional statement is true.
+
+In other words, a while loop checks the conditional statement at the beginning of the loop, while a do while loop will check the statement at the end.
