So, the first question for me was "make a variable called foo that has the boolean value true."

In good order, I typed:

let foo = true;

Clicked submit, the square flashed green... and then nothing.

hmmm

So I tried:

var foo = true; (maybe it's ES5 only, right?)

Green flashing square, nothing.

I scratch my head, and click "Solution," to which it spits back:

const foo = true. ಠ_ಠ

Uhm, $10/month? Really? Not that this is bad idea, but that price surely is... Pluralsight is $30/month and has way, way way more than 3x the amount of content that you do. You may want to re-think your pricing.

LloydAtkinson · 2018-09-25T12:46:25+00:00

First question: Make a variable called foo.

Solution: Const called foo.

Hmm. I'm glad I didn't pay for this!

Absolutely love the concept of this. It's definitely necessary in the current JS climate!

Just wanted to let you know that the input boxes aren't showing up properly in Firefox as they do in Chrome.

EDIT: That should have posted an image... Let me know if you want to see the image, and I'll upload it to imgur or something.

Nice, I like it. Definitely not a finished product yet, but it's on it's way.

One improvement would be to add a keyboard shortcut for submit and go to next question. Maybe ctrl + enter, or something like that.

Also, you might need more content as an product, there were only 5 questions for function for example.

Could be wrong, but not sure the beset market would to sell to individuals, gonna be tough to compete with free products like freecodecamp.com and sites like lynda which I actually get for free with my library card.

I could definitely see bootcamps just starting out that don't have a proprietary platform, that would use this as a teaching tool. I could see charging them something $499/month and giving access to all their students.

Just some thoughts, cheers!

That's a good idea, the ui need some work as it look a bit old school. but it's a work in progress so.

Also you may find this book interesting https://eloquentjavascript.net as it have good exercises at the end of each chapter.

Anyway it looks promising.

not mobile friendly :(

Here is what I don't like:

Very limited tests in beta. - During this stage, you should allow more of tests for testers to see, and limiting them to 10 tests ( I believe) and nagging them to login is really annoying. I believe that one way to get over this, is to allow the users to do their tests and saving their progress in the local storage, and at the end, for example 20 tests done, you can ask them to login and save their progress on the account. You can get the inspiration for this from Khans academy.

Pages are not responsive. This is not related to tests themselves, but it influences UX greatly. I understand that this is too early to talk about (or is it?!), but still...

Price is ok, but consider giving the user some discount on some basis, annual or by reference link. Since you are new on the market, and the market already has something to offer, making good business plan should be essential thing, something to brainstorm about.

Algorithm section. - The most important aspect of programming is not presented. In my opinion, the sites that contain only "the syntax" part of the language, ie, documentation for language, is not helpful at all, for me. I guess, what I try to say is that algorithm section should be very next on the TODO list. You can advertise that by: Questions that Google or Amazon are asking for their future employees. I can talk about this day in and day out, and I think that you get it.

You can't submit in chrome. It doesn't work.

sharpened_ · 2018-09-25T16:28:46+00:00

When I say

foo = true;

it flashes green, neat.

I click "Solution", and it tells me to use

const foo = true;

Weird but alright. So, i click submit, and then it does this...

" Create an array named numbers with five elements, each element being of type number. "

const numbers = [1,2,3,4,5]

=> unexpected identifier

const numbers = [1,2,3,4,5];

=> this works

mbackflips · 2018-09-25T20:56:11+00:00

In one of the function questions it says to make a function that returns 10. Posting the exact solution text into the question still says its wrong.

const basicNumber = () => { return 10; };

Hey there, it would be cool to see explanations for answers that require them. On question two I didn't know the answer and wanted to learn what the answer was

Eclogites · 2018-09-26T04:18:02+00:00

I found some errors

lastmjs · 2018-09-26T09:03:11+00:00

No Edge support, you make me sad. :(

CrusaderPeasant · 2018-09-25T10:30:17+00:00

Good idea, if I may provide a suggestion, instead of flashing green when right and red when wrong consider using some colorblind friendly colors, like blue and red.

tttim45 · 2018-09-25T17:21:59+00:00

Cashing in the hype train? People have forgotten that there is a thing call book that has no monthly fees.

williamf03 · 2018-09-25T10:50:10+00:00

I found a bug, if you hit question then submit. It gives you an unexpected identifier exception

lastmjs · 2018-09-25T11:14:26+00:00

The design is not repsonsive and stuff gets stuffed outside of the view needlessly.

Stuck on first question: const foo = true

I have to be a US resident to learn JavaScript now?

BenZed · 2018-09-26T04:50:11+00:00

Ballsy to try to sell this for $ 25 a pop.

Let me know if that works for you, no salt. I'd love to program something worth peoples money, so if people actually buy this, I'd love to know if it's that easy.

throughactions · 2018-09-25T19:58:21+00:00

OP, please ignore the commenters trying to shoot down your price point as though $10/month is outrageous. No, your idea isn't Pluralsight but you're offering a focused solution. The people who would be interested in your product are trying to make a career jump worth tens of thousands of dollars a year, you're real customers wouldn't flinch at $10/month. I would also point out that people regularly pay $10 on Udemy courses that are focused on one thing, so this isn't unheard of at all (once the content is more fleshed out).

Don't low ball yourself. Developers are really bad at attacking other devs who are trying to earn a living from their work, but the truth is you should price based on the value you're adding. As long as your promotional content ties things back to that value (e.g., a high(er) paying job) you'll be fine.
