How to 'continue' inside a each loop : underscore, node.js

The code in node.js is simple enough.

_.each(users, function(u, index) {
  if (u.superUser === false) {
    //return false would break
    //continue?
  }
  //Some code
});

My question is how can I continue to next index without executing "Some code" if superUser is set to false?

PS: I know an else condition would solve the problem. Still curious to know the answer.

_.each(users, function(u, index) {
  if (u.superUser === false) {
    return;
    //this does not break. _.each will always run
    //the iterator function for the entire array
    //return value from the iterator is ignored
  }
  //Some code
});

Side note that with lodash (not underscore) _.forEach if you DO want to end the "loop" early you can explicitly return false from the iteratee function and lodash will terminate the forEach loop early.

Instead of continue statement in for loop you can use return statement in _.each() in underscore.js it will skip the current iteration only.
