Practice entries in config.json

[colinleach]

With 25 concepts on the board, maybe it's time to add some more practice exercises. - or at least think about it This starter list isn't at all definitive, just something to start a conversation.

I've tried to pick out exercises which are both easy and fairly well focused on one or two concepts, rather than a whole-language workout.

Is it expected to have a non-zero intersection between practices and prerequisites?

[colinleach]

I think so, but I'll check. There should be plenty of time for that - I'm far from confident that these are the best choice of exercises and concepts.

[depial]

I think I misunderstood the structure... The concept should be finished first, which is the prerequisite, then the practice exercise practices the concept, right?

[colinleach]

Err... I think so. Please don't assume I know what I'm talking about!

Another (somewhat related?) thing I could float here is to add Tuples to the prereqs for Composite Types.

I feel that the topics are related, and Tuples is just kinda hanging freely out there as a leaf. I'm not sure how you'd feel about that idea, though.

add Tuples to the prereqs for Composite Types

I was going to agree with this, then I looked more closely at the config.json and realized we have a different problem. In my head, and on the flowchart, Tuples is a prereq for functions, which is in turn a prereq for Types (and all that follows below). Somehow, we/I missed this off the entry for Locomotive Engineer.

{
        "slug": "locomotive-engineer",
        "name": "Locomotive Engineer",
        "uuid": "3341044c-6dd6-4a7b-a841-3a1215cd177b",
        "concepts": [
          "functions"
        ],
        "prerequisites": [
          "vector-operations",
          "pairs-and-dicts"
        ],
        "status": "beta"
 }

I think the better fix is to add tuples here, as it should long have been!

Another PR incoming...

[colinleach]

You approved these. Does that mean you want them merged as-is?

[depial]

If that's how the prereq structure should be, I'm fine with the selection you've made. So you can merge at will :)
