This looks great guys! I especially like the tutorial flow.

Some criticism: You should show JS syntax errors instead just showing a generic error message. I understand you don't want to scare newbies away with compiler errors, but your solution just makes debugging more difficult.

You should show syntax errors, but translate the default JS error messages into something friendlier. Codecademy does this for their intro lessons.

That Heroku video you link to on the Dev Tools page is about 4 years old, and is demoing a version of the product that no longer exists (their attempt at an online IDE of sorts).

Looks like a great product, though! Keep it up.

I don't understand why we cant skip around the lessons in the python tutorial. I don't need to start at lesson 1; i want to skip around to different lessons.

> I don't need to start at lesson 1; i want to skip around to different lessons.

There's a good reason for this, which I will explain with an analogy:

Lesson 1: Write the Great American Novel.

Lesson 2: Learn how to write engaging, readable short stories.

Lesson 3: Learn how to write internally consistent essays.

Lesson 4: Learn how to write coherent paragraphs.

Lesson 5: Learn how to structure grammatically correct sentences.

Lesson 6 Learn how to use and spell common English words.

Lesson 7: Learn how to enter text on a keyboard.

Get it? Lessons have a natural order, and each lesson requires what was learned beforehand.

I get it. It's just that I'm not a beginning programmer. I mean, unless the site is only for novices with zero programming skill, you're requiring all intermediate programmers to relearn stuff they've already mastered.

Also, I wanted to browse around the lessons in order to evaluate the quality of the site so that I could decide whether to recommend the site to non-programmer friends.

> It's just that I'm not a beginning programmer.

That should have been the first thing you said. :)

But such tutorials are obviously for rank beginners, experienced programmers don't use these kinds of sites. Unless it's a dramatic jump, like from COBOL to Haskell, to learn a new language they go straight to the language's documentation:

Python 2:

http://docs.python.org/

Python 3:

http://docs.python.org/py3k/

I'm mentoring a few people learning Python, and I wanted to quickly evaluate LearnStreet and decide whether to recommend it.

With Codecademy I could do that, here I cannot. So Codecademy it is.

Skipping is a really important feature for those who you hope would promote your service for you :-)

We will be adding this very soon.

On your javascript tutorial, it kept giving me an error when I typed in the string "Javascript" as it instructed.

Hey, can you email feedback@learnstreet.com and we'll help you out. Thanks.

Nice job it looks really good.
