Matching iterating values in js when iterating with a higher step count than 1

Question

How do I match values when I use a different iterating step count other than 1?

Please see the example below. I am interating by 5 since 5 is the speed.

But, how do I stop once I come close to 53. How do I detect and stop start from going way past 53 and make it 53?

var start=0;

var value_to_reach=53;
var increment_speed=5;
while(true) {


if(start>value_to_reach) 
{
start-=increment_speed
} else { start+=increment_speed  }



if (start==value_to_reach) { 
console.log("reached :" + value_to_reach); //Obviously this will never happen with the increment being +5."
    }
  if (start>54)
    {
    console.log("Let's break this loop for the sake of stopping this infinite loop. But we couldn't achieve what we want. Not reached " + value_to_reach); 
      break;
    }
}

How to detect if it's close to 53 or not

You can get total steps by this:

var totalRepeation = Math.ceil(value_to_reach / increment_speed);

And so you can create counter that increment one by one and check to see last step.

You can try this one:

var start = 0;

        var value_to_reach = 53;
        var increment_speed = 5;

        let totalRepeation = Math.ceil(value_to_reach / increment_speed);

        let i = 0;
        while (true) {
            
            if (start > value_to_reach) {
                start -= increment_speed
            } else { start += increment_speed; i++ }

            if (i + 1 >= totalRepeation) {
                console.log("you are close to 53. the start numbre is: ", start)
                break;
            }


            if (start == value_to_reach) {
                console.log("reached :" + value_to_reach); //Obviously this will never happen with the increment being +5."
            }
            if (start > 54) {
                console.log("Let's break this loop for the sake of stopping this infinite loop. But we couldn't achieve what we want. Not reached " + value_to_reach);
                break;
            }
        }
