// 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
