How does CoffeeScript work with inserting code into HTML with <script type="text/coffeescript"> tags?

Arjun

9:32 AM

@Qwerp-Derp I am sure that it won't work without a dependency. See this.

Qwerp-Derp

@Arjun I know that, but how does embedding CoffeeScript even work?

Arjun

@Qwerp-Derp Well, that dependency transpiles the code present it any script tag with type=text/coffeescript and executes it. Since bowser only knows, type=text/javascript, it skips that <script> tag

Anonymous

I remember reading that Chrome will start complaining on script tags that have types other than text/javascript

Anonymous

That's one of the reasons why I'm having to rewrite all my brython projects in pure JS

Arjun

@Mego Yes, that's why it's a bad practice.

@Mego But one can do something like <div class="coffeescript-code">#Code</div>, CSS : #coffeescript-code{display:none;}. And that dependency can get the content of that <div> and execute it.

Square pyramidal number

In mathematics, a pyramid number, or square pyramidal number, is a figurate number that represents the number of stacked spheres in a pyramid with a square base. Square pyramidal numbers also solve the problem of counting the number of squares in an n × n grid. == Formula == The first few square pyramidal numbers are: 1, 5, 14, 30, 55, 91, 140, 204, 285, 385, 506, 650, 819, ...

@Adnan What do A and ‡ do

A = alphabet, ‡ = translate

maybe not the best example

It is probably not a useful command in general though

In Actually, there's two way to do maps. The first way is ⌠code here⌡M. It maps the function literal over an iterable. The second way is ♂f (where f is some single command), which is shorthand for ⌠f⌡M.

Erik the Outgolfer

CJam has the same, either {code here}% or :f

Anonymous

And then there's ♀, the binary map operator. ♀f is equivalent to Z⌠if⌡M (Z is zip and i is flatten).

Erik the Outgolfer

CJam has .f (vectorize)

e.g. [1 2 3 4 5][1 2 3 4 5].+ -> [2 4 6 8 10]

@Qwerp-Derp By using the values of the square pyramidal number sequence ((1,1), (2,5), (3,15), ...) and applying the method of divided differences, you can get what's called a Newton polynomial. That polynomial, when evaluated at positive integer values of its parameter, will yield the corresponding value in the sequence.
