+// When is a for loop better than a while loop?
+
+//for loop is better when you want to run code a certain number of times, 
+//while is better when you want to keep running that code until the condition.
+
+
+// How is the readability of the code affected?
+
+//I think for loops are more concise, and your variable is set within the loop,
+//in while loops looks like you have to set the variable beforehand.
+
+
+// What is the difference between a for loop and a for...in loop?
+
+//for in loops are better suited for objects
+
+
+// What is the difference between a while loop and a do...while loop?
+
+//in while loops, test expression is checked at first but, in do...while loops code is executed at first then the condition is checked
