在函数调用中中断或继续循环

Question

My question is: How can I trigger a break; or continue; for a loop through a function that gets called? The thing is, I do not want to nest all possible conditions within a loop to avoid code complexity. I was thinking about some pseudo example:

var someObjects = [...] //array with some js objects    

for (var i = 0; i < someObjects.length; i++) {
  var element = someObjects[i];
  doSomething(element);
}

function doSomething(object) {
  //some code here
  if (somethingIsDefined) {
    doSomethingElse(object);
  }
}

function doSomethingElse(anotherObject) {
  //some more code here
  if (somethingMatches) {
    //here i would like to break the most upper loop
  }
}

//someObjects will be processed

I know that it would be possible to introduce for example a boolean variable and check within the loop if it is true or false and depending on that, break; or continue; .
But this - even if it is just one line - would increase the nesting. Do you see any possible solutions?

If you are using the Underscore library , which I recommend, you could write the following:

_.any(someObjects, doSomething);

function doSomething(object) {
  //some code here
  return somethingIsDefined &&
    doSomethingElse(object);
}

function doSomethingElse(anotherObject) {
  //some more code here
  return  somethingMatches;
}
