    This was asked the other day: http://stackoverflow.com/questions/38306912/i-want-the-pattern-printing-using-javascript/ (Although that other question was asking about "printing" the grid, not returning an array of arrays - if an array of arrays is even what you mean with that `[()()()]` notation. But if you can achieve one you can likely achieve the other.) – nnnnnn Jul 14 '16 at 05:25

Basically you could generate a nested array and fill it with the right value with a check if one index is zero or the last possible index value.

var n = 5,
    array = Array.apply(null, { length: n }).map(function (_, i) {
        return Array.apply(null, { length: n }).map(function (_, j) {
            return +(i === 0 || i + 1 === n || j === 0 || j + 1 === n);
        });
    });

console.log(array);
