Looking at the javascript authority guide today, I found that there are two types of break syntax (break; And break the label) . I didn't look at it very carefully before. It's on the first few pages.
But I don't know how to write the label, so I looked it up on the Internet and found an example
This will break the whole loop nesting!!
(c, Java break is like this, not serious reading ah...)

function foo ()
{
dance:
for(var k = 0; k < 4; k++){
for(var m = 0; m < 4; m++){
if(m == 2){
break dance;
}
}
}
}
This will break the whole loop nesting!!
