break - 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 the while loop from the if statement. So far, the best method seems to be the goto method that is non-existant in Javascript. What is the best way to cause the if statement to break out of both of the loops it is nested in? Thanks in advance for the help!

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.
