Kata

This kata is a subject to deduplication process here: https://github.com/codewars/content-issues/issues/73 Please join the discussion to share your opinions, and help us identify duplicate kata and retire them.

the kata is either ranked wrongly, or its Unit Test has a mistake, it's missing function call. so i decided to call my function addSumMethod but, for the Unit Test in order to succeed this function must be called before testing.

So, this is how Sample Test must look like:

describe("Tests", () => {
  it("test", () => {
    var tests = [
      [[1,2,3,4], 10],
      [[2,4,6,8], 20],
      [[93, 31, 62, 103], 289],
      [[397, 403, 764, 142], 1706]
    ];

    addSumMethod(tests);
    
    tests.forEach(function (x) {
      Test.assertEquals(x[0].sum(), x[1]);
    });
  });
});

And, tbh, i think the author should have done it themselves. With this small hack in Unit Test now it passes the SampleTest, but Attempt still fails :(

Nice one! I would rate it as 6kyu thnx

Good Kata, keep it up :D I ranked it 6kyu for the OOP and altering prototypes involved.

Math.random should be called before the test loop, not in the condition (=> on every iteration).
