I would like to know if it is possible to create a multidimensional array already setting values in it.

In php for example, it is possible for me to do:

$data['teste1']['teste2']['teste3'] = 'valor';

That automatically creates an array with the indices one inside the other. Would it be possible following the same principle to do the same thing in Javascript?

When i do

const data = [];
data['teste']['teste2']['teste3'] = 'valor'

I get the message "Cannot read property 'teste2' of undefined".

What I find strange is that for the first index ('teste') it is created, it just doesn't find/create the second index

The only way I found to solve this was by defining each array index and setting an initial value and then pushing this new array

game['goals'] = {
     '0,5': {over: 0, under: 0},
     '1,5': {over: 0, under: 0},
     '2,5': {over: 0, under: 0},
}

game['handicap'] = {
     '0,5': {over: 0, under: 0},
     '1,5': {over: 0, under: 0},
     '2,5': {over: 0, under: 0},
}

data.games = game
