+// Zig 'while' statements create a loop that runs while the
+// condition is true:
+//
+//     while (condition) {
+//         condition = false;
+//     }
+//
+// Remember that the condition must be a boolean value and
+// that we can get a boolean value from conditional operators
+// such as:
+//
+//     a == b   a equals b
+//     a < b    a is less than b
+//     a > b    a is greater than b
+//     a !=b    a does not equal b
