Do you know of anyone who learned programming by starting with CoffeeScript?

I'm not trying to resurrect the old debate of whether or not you should
learn JavaScript before CoffeeScript: I think there's been enough written
on that already.

I'm just really interested to hear about actual cases of starting out with
CoffeeScript as the first programming language.

I'd have to think that the number of people who's first language is
CoffeeScript would be a small number.

It's very hard to work with JS (CS only partially soves the problem, for
example - working with collection is still a fucking hell) without good
understanding of different programming concepts.

Try ruby, lisp, python, ....

I mean this:

_(params).extend a: 1
_(_(list).filter(fnA)).reduce(fnB) (with .chain() it also looks ugly)

CS support comprehensions, it eases it a little but it's still not a
replacement for a good collection API.

Sorry, can you explain more? The code snippet doesn't make any sense to me.
The _ function seems to be some sort of wrapper? I'm guessing to return a
collection type with special methods like filter() and reduce()? If so, why
is there a need to wrap the results of filter()?

Yes, You are right, that was a poor example, both `filter` and `reduce` are
standard JS methods and available directly on Array.

But, there are lots of other methods that aren't available, thats exactly
the reason libraries like http://underscorejs.org exists.

For example You frequently need to

- extend object with another object
- more flexible way to sort an arrays than Array.sort can provide (take a
look at `underscore.sortBy`)
- have handy Array.first() and last()
- would be nice to have sort of `Array.has` method (instead of indexOf(v) >
0)
- Array.reject (opposite of Array.filter)

and so on ...

Even worse - it's not easy to create Your own implementations of
collections (Backbone has to use `collection.get(id)` because it's
impossible to do `collection[id]` for custom collection in JS) an so on,
standart loops won't work for custom collections either.

That's what I meant by poor support for collection.

I may be roughly one of this kind of people...
I tried to learn Python, JS, Haskell before and failed to get familiar with
a language.
Then I come across CoffeeScript and begin to write programmes in Chrome and
Node with it.
Now most of my code on Github is in CoffeeScript. Though I'm not an
experienced coder - -!.

And I think CoffeeScript already contains all basic features one should
know about programming.
A problem is.. it's quite hard for one who only learnt CoffeeScript in
China.
But I think the more readable code fits me better than JS which contains
too many flaws..

True.
In China, you will learn C/C++ or Java in university.
And JavaScript is very common at company.
But CoffeeScript, Backbone is used very few by companys in China.

I have had friends that know java, get a job coding javascript and just
skip learning javascript all together and go strait to coffeescript.

I would definitely recommend skipping javascript and going strait to
coffeescript

Unless I'm missing something, you simply cannot program CS without knowing
JS.  Indeed, many of us are learning the JS core capabilities by staring at
the JS produced by CS.  Here's a great quote from Trevor Burnham's
CoffeeScript book:

This book helps readers become better JavaScripters in the process of
learning CoffeeScript. What’s more, it’s a blast to read, especially if you
are new to Coffee- Script and ready to learn.

Maybe… in the short term… perhaps if you are thinking 6 months into the
future and need to get a project out the door, but you cannot possibly be
an efficient frontend developer without knowing JS as well as you know CS.
Mainly because you will undoubtedly have to use other people's libraries,
and they will be written in vanilla JS. If you can't understand that code,
you're left in a poorer position any 3rd party code has bugs in it or
doesn't do what you want it to do. Plus, if you're doing open source stuff,
you should do it in vanilla JS to maximise the number of possible
contributors.
