Question

Which of the following loops creates an infinite loop?

Answer 1
for (var i = 0; i < 10; i++) { }

Answer 2
for (var i = 0; i < 10; i--) { }

Answer 3
for (var i = 10; i > 0; i--) { }

Answer 4
All of the Above

Answer 1

I only know a tiny bit of code/coding logic but

a for loop starts with an input (in this case, i = 0), applies a condition (in this case, i > 0 or 10 or whatever), and if the condition is met, it executes the following code (in this case, i-- or i++)

so for the first example, it starts with i = 0, checks to see if i < 10, and if i is less than 10, it executes i++, which increases the value of i by 1. this keeps going as long as the condition is met. however, in code 1, i will eventually not be less than 10, so the loop terminates. that's why answer 1 is not correct, as this is not an infinite loop

keep going with choices 2 and 3 and you'll see that one of them is an infinite loop b/c the condition is always satisfied

Answer 2

I got it. Thanks though
