/**
 * underscore each Simulation for loop 'continue' and 'break' keyword
 */

var datas = [1, 2, 3, 4, 5, 6, 7];

_.each(datas, function(data, k) {
    console.log(data, k);
    if(k === 2) {
        console.log('continue');
        return;
    }
    if(k > 4) {
        console.log('break');
        return {};
    }
    console.log('test');
});

Interesting. However, IMO it's even simpler with _.every.
returning false will break the loop and returning true will continue the loop.

every_.every(list, [predicate], [context]) Alias: all
Returns true if all of the values in the list pass the predicate truth test. Short-circuits and stops traversing the list if a false element is found.
