You can use the Bubble sort algorithm to sort an array of numbers without the sort function in JavaScript. There are many different sorting algorithms.
JavaScript sorts an array of numbers without the sort function
Simple example code.
<!DOCTYPE html>
<html>
<body>
<script>
function bubbleSort(array) {
var done = false;
while (!done) {
done = true;
for (var i = 1; i < array.length; i += 1) {
if (array[i - 1] > array[i]) {
done = false;
var tmp = array[i - 1];
array[i - 1] = array[i];
array[i] = tmp;
}
}
}
return array;
}
var numbers = [12, 10, 15, 11, 14, 13, 16];
bubbleSort(numbers);
console.log(numbers);
</script>
</body>
</html> Output:
If you want to sort a string in javascript without using a built-in method, just by using for’s and comparisons like ‘a’ > ‘b’.
Use the Below program, which produces the expected output from your program using selection sort.
swap and replace functions work fine.
function sort(str) {
var sorted = str;
//Selection sort
for (var i = 0; i < str.length; i++) {
for(var j = i + 1; j < str.length - 1; j++) {
if (str[i] < str[j]) {
str = swap(str, i, j)
}
}
}
return str;
}
console.log(sort("zaasfweqrouoicxzvjlmmknkniqwerpopzxcvdfaa"));
