Array Object sorting is not working for large length data in Javascript?

Question

Today I came across with one issue, I don't it this issue is coming because of code or bugs in Javascript. I tried to sort object array, which is like this

const array = [{
text:'one'
count:5
},
{
text:'two'
count:5
},
{
text:'three'
count:5
},
{
text:'four'
count:5
}]

Now I need to sort the object array based on the count index. I tried with these piece of code

Array.prototype.sortBy = function (p) {
          return this.slice(0).sort(function (a, b) {
            return (a[p] > b[p]) ? 1 : (a[p] < b[p]) ? -1 : 0;
          });
  }
   console.log(array.sortBy('count'))

Here sorting is working fine when I have object array length as less than 100, but won't work when I have more than that length. I tried with some Npm packages also. But it doesn't work. Help me

What exactly do you mean by "won't work"? Are you getting errors? Is it not sorted at all? Or badly? Please be specific and ideally create a minimal reproducible example. It works for me with a length of 200: jsfiddle.net/khrismuc/bdfgs624 — user5734311

You're making it too complicated for no gain, you can just rely on the .sort method

Here is a codepen to show it working with 500 elements, just to be sure

const array = [{
    text: 'one',
    count: 3
  }, {
    text: 'two',
    count: 1
  }, {
    text: 'three',
    count: 2
  }, {
    text: 'four',
    count: 4
}];

let sorted = array.sort((a, b) => a.count - b.count);

console.log(sorted);
