Why does table[0][0] = 2 not only assign that value to the first item in the first array?
let table = new Array(3).fill(Array(3));
table[0][0] = 2;
console.log(table);output: [ [ 2, , ], [ 2, , ], [ 2, , ] ]

1Because `fill` uses references to the same array object to fill the nested array. – Heretic Monkey Apr 02 '21 at 12:50

@JamesJavascript I had this same issue a while back trying to do `.fill([])`. Instead of using `.fill(Array(3))` here, use `.fill().map(e => Array(3).fill())` – Brandon McConnell Apr 02 '21 at 14:54
