JavaScript sorts numbers in an array in order of size

Question

I am a newbie who just started learning, and I don’t know much. During my study, I found that the arrays are not completely arranged in size order when sorted using sort(). It has something to do with the number of digits, so I thought that I I tried to arrange the array in order from small to large, and typed some code myself, but in the end there was still a problem. Please explain and correct me.%

Answer 1

It is recommended that if you want to write sorting by yourself, you can download the sorting method on Baidu. I personally recommend bubble sorting method.

Answer 2

<script>function myFunction(){	var fruits = ["21421", "421421", "Apple", "Mango"];	fruits.sort();	var x=document.getElementById("demo");	x.innerHTML=fruits;}</script>

I tried it and there seems to be no problem
