You can assign a label identifier to any block of executing statements, including control structures. The purpose of the label is to allow break and continue statements within deeply nested control structures to exit to a nested level that may be at levels beyond the scope of the normal break and continue statements.

 
Example
  
outerLoop:
for (var i = 0; i <= maxValue1; i++) {
    for (var j = 0; j <= maxValue2; j++) {
        if (i == magic1 && j == magic2) {
            break outerLoop;
        }
    }
}
