JavaScript: Returns a subset of a string

JavaScript Object: Exercise-7 with Solution

String Subsets

Write a JavaScript program that returns a subset of a string.
Sample Data: dog
Expected Output: ["d", "do", "dog", "o", "og", "g"]

Sample Solution:

JavaScript Code:

String.prototype.sub_String = function() 
{
  var subset = [];
  for (var m = 0; m < this.length; m++) 
  {
    for (var n = m+1; n<this.length+1; n++) 
    {
      subset.push(this.slice(m,n));
    }
  }
  return subset;
};

console.log("dog".sub_String());

Output:

["d","do","dog","o","og","g"]
