The information here 
is part of two printed
references, that
VisiBone makes, the
JavaScript Card:

a dense, laminated,
four-page 8.5x11 book

and also the
JavaScript Foldouts:
  
a set of three fan-fold
booklets with larger
print and smaller
folded size.

 
Does it look busy?
Well, it wasn't meant
for idle people!

Here are all the
features of client-side
JavaScript, in
living code.

English takes a
back seat here.  
To make solid 
code, learn to 
read, think and 
write in
JavaScript.
Fluency will
serve you best
in the end.

The assert()
function is the best
invention for
programming
since the subroutine.

Not only will its
proper use make
your software
test itself, earning
and protecting
reliability from the
start.

But it's a clear,
concise way to
describe exactly
what all the features
of JavaScript do.

Regular Expressions
are very versatile for
validating or
analyzing strings.

See the JavaScript
Regular Expressions
reference.

If you are looking to
establish or extend
your business in
international markets,
it is very important to
ground your company's
brand and presence in
targeted countries. The
first step in a successful
strategy is to register
an international domain
for your company.
International domain
registration can be
tricky, so use a
registrar that knows
the requirements and
process is important.

The assert() function
is like a video camera. 
Hold on now, this will 
make sense in a sec.

Think how you first learn 
human language. You 
observe words spoken 
and their effects. 
Person A: "I'm hungry" 
Person B gives A food. 
You infer an association 
between making the 
sound "hungry" and 
getting fed.

This card can teach you 
JavaScript not by talking 
about it but by doing it 
and (here's the part I'm 
smug about) showing 
you the effects. The 
assert() function is a 
great way of showing 
you what JavaScript 
code does.

Imagine, instead of a 
dead-tree dictionary 
that defines words in 
terms of ... other words, 
it would instead show 
a video clip of people 
using and responding
to those words.

Assert makes the 
effects of JavaScript 
code visible, just like 
this video-dictionary 
would make the 
effects of human 
words visible.

VisiBone also makes
several printed web
color references.

Thank you, and good luck building!

An "X" in row "Yyyyy" means code under <script language="Yyyyy"> will run
in the browser for that column.  For example:

     IE6/PC
     ------
     <script language="JavaScript 1.3">
          // runs
     </script>

     Netscape 6
     ----------
     <script language="EcmaScript">
          // ignored
     </script>

(Yes, there are two radically different browsers both claiming to be IE4.01,
one claims to support JavaScript 1.3 and EcmaScript, and exceptions work
perfectly, and the other not.)

See the Error section for a trick on how to include code with exceptions.
