遍历

    var data = [[1, 11], [2, 22], [3, 33], [4, 55], [5, 88], [6, 143]]
    for (var i = 0, j = data.length - 1; i < j; i++) {
        data[i][1] += data[i + 1][1];
    }
    console.log(data)

var a = 11, b = 22;
document.write(a,"<br />");
document.write(b,"<br />");
for (var i = 0; i < 20; i++) {
	var z = a + b;
	a = b;
	b = z;
	document.write(b,"<br />");
}
