mozilla 官网js实例中有个不理解的地方，求解
讲continue的地方
var i, j;
loop1:
for (i = 0; i < 3; i++) { //The first for statement is labeled "loop1"
loop2:
for (j = 0; j < 3; j++) { //The second for statement is labeled "loop2"
if (i == 1 && j == 1) {
continue loop1;
} else {
console.log("i = " + i + ", j = " + j);
}
}
}
// Output is:
// "i = 0, j = 0"
// "i = 0, j = 1"
// "i = 0, j = 2"
// "i = 1, j = 0"
// "i = 2, j = 0"
// "i = 2, j = 1"
// "i = 2, j = 2"
// Notice how it skips both "i = 1, j = 1" and "i = 1, j = 2"
