Breaking out of an outer loop from an inner loop in javascript

Question

while(valid){
   for(loop through associative array){
      if(!valid){
         break;
      }
   }
}

I have tried to find a way to break out of t

Answer 1

Creating a variable to act as a flag to pass to the outer loop is one way, however, JavaScript provides labels which I think makes the code easier to read as well as reduce the amount of code:

outerloop:
while(valid){
    for(loop through associative array){
      if(!valid){
         break outerloop;
      }
   }
}

Here's some info on labels here Scroll down to the label section. You could even do a continue to the outerloop.

Answer 2

Depending on what your conditionals are, it should be easy to set the iterator of your for-loop to something that would break it, and set your while condition to false. For example,

while(someBoolean){
    for(var i = 0; i < size; i++){
        if(wantToBreak){
            i = size;
            someBoolean = false;
        }else{
            //Do Stuff
        }
    }
}
