Example 1: how to create an array in python

#prints: ['1st', '2nd', '3rd']
array.append("4th")

Example 2: javascript fill 2 dimensional array

const fillSquareMatrix = (size) => {
  return Array(size)
    .fill()
    .map((u,y) => Array(size)
         .fill()
         .map((u,x) => y * size + x + 1));
};

console.log(fillSquareMatrix(3));
