“Continue” in Lodash forEach

In Lodash, on the other hand, returning false tells _.forEach() that this iteration will be the last. Is there a way to make the “continue” behavior also functional in Lodash?

You could return true, or just a single return (which returns undefined), this value is different from needed false for “exit iteration early by explicitly returning false.”

_.forEach([1, 2, 3, 4, 5], function (a) {
    if (a < 3) return;       // continue
    console.log(a);
    if (a > 3) return false; // break
    // return undefined;     // continue, undefined is the standard value of ending a function
});
