The website I created seems to be stuck in an infinite loop, preventing it from fully loading due to the continuous execution of code in JavaScript

The web page I created to calculate the number of possible 3-digit numbers using only the digits 1 - 6 in ascending order is not loading. I suspect there may be an error in the while loop section of the code below. I attempted to replicate the same output as the string '{a:4, b:5, c:6}', but encountered issues with it. Similarly, using 'a:4, b:5, c:6' also did not yield the desired results.

    var n = 0;
    var o = {a:1, b:2, c:3};
    var i = [o.a, o.b, o.c];
    var s = i.sort(function(a, b) {
        return a - b;
    });
    while (o != {a:4, b:5, c:6}) {
        o.c++;
        i = [o.a, o.b, o.c];
        if (o.c = 7) {
            o.c = 1;
            o.b++;
        }
        if (o.b = 7) {
            o.b = 1;
            o.a++
        }
        if (i == s && o.a != o.b && o.a != o.c) {
            n++;
            document.getElementById('a').innerHTML = n;
        }
    }

Furthermore, someone's suggested question differs from mine. While I am focused on resolving the issue of the page not loading and fixing the while loop, the other individual raised a query regarding why two empty objects are not considered identical.

Answer №1

It seems that the initial question posed by someone is not quite aligned with my own query. My concern revolves around why the webpage fails to load and how to rectify an issue with a while loop, whereas the other individual focused on why two empty objects are not identical.

In essence, both queries are intertwined. Your code perpetuates the loop based on the condition o != {a:4, b:5, c:6}. However, this condition will never evaluate to false, leading to an infinite loop.

To address your inquiry regarding the page loading hiccup, the explanation is rather straightforward: JavaScript execution halts the rendering process of the page. As long as your code runs continuously, rendering is interrupted, resulting in nothing being displayed. A potential quick fix could involve delaying code execution post-render:

function theCodeYouPosted() {
}

// introducing a delay of 100 milliseconds before executing your code
setTimeout(function() {
  theCodeYouPosted();
}, 100);

While there are numerous workarounds like this one, they merely mitigate the issue temporarily without addressing the root problem - the unending loop.

You must devise a condition that accurately compares all three sought-after values. Take time to understand your conundrum instead of rushing for a solution. A meticulous property comparison approach might resemble:

while(!(o.a === 4 && o.b === 5 && o.c === 6)) {
  ...
}

Additonally, multiple flaws may exist within your codebase. Utilize the debugger tool and delve into comprehending the functionality of your written code.

A convenient method involves triggering F12 in your browser and inserting a debugger statement prior to the section you aim to dissect.
