"Continue" in Lodash forEach

Question

I was looking over the differences between the Underscore and Lodash libraries and I came upon one issue regarding _.each / _.forEach.

In Underscore, the _.each function cannot break out of the looping. When using return false, it only worked as a "continue" statement. (which was the intended functionality in my case) = It forces the next iteration of the loop to take place, skipping any code in between.

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?

Thanks.

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  });
