but it is not enforced

It specifically states to use DML not DDL

Easy to read and understand!

Hello trying to learn python. I feel stumped by many of the problems. It would be helpful to know what resources you all use to help find solutions. I am a newbie and willing to learn.

I feel so dumb. First time doing some c++ katas, how do I include the standard library?

It is possible to use console.log straight into the code mirror and messages will be outputted in the output panel instead of the browser console.

I think it's easier to try your code on your computer throught NodeJS. Once your code is debugged and it works you can copy & paste your solution.

You can just print the input in your functions, it's enough for debugging this.

Moreover, you can event print the preloaded dictionary if you can't live without IDE. :)

Aha! Yes I looked at indexOf for a moment, but I just read the description briefly and thought that there was only 4 valid smileys. This changes everything. ;)

As Joz said there are more than 4. Regex takes care of that smoothly, if you list them all in an array you might forget some. So any smiley having : or ; as eyes, - or ~ as a nose(or no nose) and ) and D as a mouth. Also to find if an item in present in an array there are simpler ways: check out this or this.

So I just started with JS and I can't figure out how to print debugging messages. I've tried both console.log("Someting"); and alert("something"); But they don't work.

Same problem here: text = iidqubkywkvbpgnhphzuvyjiysffqqxrddjr rule = 297 expected:<[????????????????????????????????????]> but was:<[????????????????????????????????????]>
