Trying to create multi-dimensional arrays programmatically

Question

Im testing my ability to create multi dimensional arrays with for loops with:

        for (var a = 0; a < 3; a++){
            var pax[a] = new Array();
            pax[a].push(1,2,3);
        }

        console.log(pax[2][1],pax[0][0]);

But its giving me a syntax error unexpected token at the [ of var pax[a]

I think it actually might be a scope error vs a syntax error, but I cant be sure.

var pax[a] is invalid syntax. Isn't the console telling you that? — Barmar

pax is a variable, pax[a] is an expression that refers to an element from the array or object that's the value of the pax variable. — Barmar

as a side note, the preferred JavaScript syntax for arrays is var pax = []; — jasonscript

syntax issue as @Barmar pointed out.

try...

var pax = new Array();
 for (var a = 0; a < 3; a++){
    pax[a] = new Array();
    pax[a].push(1,2,3);
}

console.log(pax[2][1],pax[0][0]);

The updated code is correct, but it's not a scope issue. JS has function scope, not block scope. It's a syntax issue.
