freeCodeCamp Challenge Guide: Prevent Infinite Loops with a Valid Terminal Condition

Prevent Infinite Loops with a Valid Terminal Condition 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 inc…

In this challenge it says, stop the loop when i does not equal 4 ( i !=4)
The loop never equals 4 so surely the loop never runs?
but the exercise reads like the loop is infinite?

I don’t understand why the loop isn’t i === 4… although, did i read somewhere this statement always has to be < or > as it’s sort of counting through…as opposed to being just stagnant i guess at this specific point…

so is this why !=4 works because its like the opposite of a fixed point?

…may have just answered my own question…

!= 4 does not work. That’s the entire point of the challenge.

In a for loop, we have

for (initialization; loop condition; incrementor) {
  body
}

The loop runs the initialization, then it executes the body of the loop and then the incrementor until the loop condition is false.

In this case, i != 4 is always false and the loop never stops running.

Thanks! sorry, silly question!
I think i was over thinking it!
