push to column in 2d array syntax?

[LightandSound]

array[index][index2] = array2[index][index2] works fine, any form of push (array[index].push etc just fails with cannot assign. Any clue on the correct syntax?

Here's an example.

const var my2darray = [[],[]];

my2darray[0].push(58);
my2darray[0].push(59);
my2darray[0].push(60);

my2darray[1].push("dog");
my2darray[1].push("cat");
my2darray[1].push("fish");

Console.print(my2darray[1][1]);

@d-healey so you have to array.push([]) first if you want to start pushing in to a new end column, that's where the issue was. Cheers!
