break and continue labels

Break and continue statements can be followed by an optional label which works like some kind of a goto statement, resumes execution from the label referenced position

for(var i = 0; i < 5; i++){
  nextLoop2Iteration:
  for(var j = 0; j < 5; j++){
    if(i == j) break nextLoop2Iteration;
    console.log(i, j);
  }
}

i=0 j=0 skips rest of j values

1 0

i=1 j=1 skips rest of j values

2 0

2 1 > i=2 j=2 skips rest of j values

3 0

3 1

3 2

i=3 j=3 skips rest of j values

4 0

4 1

4 2

4 3

i=4 j=4 does not log and loops are done
