Problem Explanation
- To prevent an infinite loop, the
while-condition
must reach a terminal condition to exit out of the loop.
- So the error in this challenge occurs due to the condition -
i != 4
- in the for loop.
- If you take a closer look at the code:
function myFunc() {
for (let i = 1; i != 4; i += 2) {
console.log("Still going!");
}
}
- You will see that
i
is first initialised as 1 and after every iteration of the loop, i
is incremented by 2.
- Using this logic, after the first iteration -
i = 3
and the second iteration i = 5
, the condition i != 4
will never be met and an infinite loop will occur.
