Calculating median - javascript

Question

I\'ve been trying to calculate median but still I\'ve got some mathematical issues I guess as I couldn\'t get the correct median value and couldn\'t figure out

Answer 1

Short and sweet.

Array.prototype.median = function () {
  return this.slice().sort((a, b) => a - b)[Math.floor(this.length / 2)]; 
};

Usage

[4, 5, 7, 1, 33].median()

Works with strings as well

["a","a","b","b","c","d","e"].median()
