Use Vanilla Javascrpt no frameworks.

Given n>=0, create an array length n*n with the following pattern, shown here for n=3 : {0, 0, 1,    0, 2, 1,    3, 2, 1} (spaces added to show the 3 groups).


squareUp(3) -> [0, 0, 1, 0, 2, 1, 3, 2, 1]
squareUp(2) ->  [0, 1, 2, 1]
squareUp(4)  ->  [0, 0, 0, 1, 0, 0, 2, 1, 0, 3, 2, 1, 4, 3, 2, 1]

Make use of multiple functions. Keep vaidation, actual work, rendering on screen in seprarate functions

function squareUp(n) {
  
}

Also make test case helper and test cases like https://raw.githubusercontent.com/tgkprog/codingbat/master/src/org/moh/academic/IcyHot.java
