@nathanallen Would you rather do challenge_b or the lab with tests.

There's definitely NOT time for both. In 25 we didn't get anywhere near completing all of that. I'm leaning towards the one with tests. I found that the wording in exercises_b rather confused students. We'd need to add a bunch of examples in there.

Another alternative might be to do a part of exercises_b as a "I-do/we-do" and still try to get to the lab too. But keep in mind I'm also planning to do (at least in my lesson-plan) a "you-do then we-do" mini-exercise with each part of exercises_a so I doubt they'll get more than a few minutes to start the lab.

Iterators Lab seems like a lot.

• Implementing iterators is hard.
• Running/interpreting test output is hard. (how did this go last time? did you intro it in class?)
• They haven't seen node yet.
  • Could it be browser based?

I agree with you that challenge_b could be better written. Although the wording is tricky it feels somewhat more "approachable".

Here's an approach I've used in the past:

var lyrics = ["line 1", "line 2", "line 3"]
karaoke(lyrics, croon)
karaoke(lyrics, shout)
karaoke(lyrics, whisper)

Consistent with https://github.com/SF-WDI-LABS/shared_modules/tree/master/01-front-end-basics/js-functions/27-28#functions-on-strings

Yes, it would be the first time they got to use node. This is already overdue but I can see how hard it would be to put the tests in a browser. Mocha supports it.

As I recall the lab with tests actually went OK, but there was insufficient time to complete it. exercise_b was actually more confusing.
The test-code itself is definitely beyond this group at this point. But the output might help them. I think that does a better job of guiding them than exercise_b does.

Agreed. Let's go with the lab and make sure they start it in class.
