How do you easily create empty matrices javascript?

Question

In python, you can do this:

[([None] * 9) for x in range(9)]

and you\'ll get this:

[[None, None, None, None, None, None, No         


        

Answer 1

I'll give it my shot as well

var c = Array;

for( var i = 0, a = c(9); i < 9; a[i] = c(9), i++ );

console.log( a.join(",") );
//",,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,"

Readable and maintainable !
