JavaScript Object: Exercise-6 with Solution

Write a Bubble Sort algorithm in JavaScript.
Note: Bubble sort is a simple sorting algorithm that works by repeatedly stepping through the list to be sorted,
Sample Data: [6,4,0, 3,-2,1]
Expected Output : [-2, 0, 1, 3, 4, 6]

Sample Solution: -

HTML Code:

<!DOCTYPE html>
  <html>
  <head>
  <meta charset="utf-8">
  <title>Bubble Sort</title>
  </head>
  <body>
</body>
  </html>

JavaScript Code:

Array.prototype.bubbleSort_algo = function() 
{
var is_sorted = false;
 while (!is_sorted) 
 {
    is_sorted = true;
    for (var n = 0; n < this.length - 1; n++) 
    {
      if (this[n] > this[n+1]){
        var x = this[n+1];
        this[n+1] = this[n];
        this[n] = x;
        is_sorted = false;
      }
    }
  }
  return this;
};

console.log([6,4,0, 3,-2,1].bubbleSort_algo());
