Javascript break specifies the tag to break the multilayer loop example

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
 
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!!

(c, Java break is like this, not serious reading ah...)
