Then don't use it. You are free to create a parser for your own language.

Look at this:

a = floor(b-z);
if (a inside(x-y)) {
  dosomething();
}

This *is* "obfuscated and convulated as possible".

1) Why is "x-y" not the *expression* of "x minus y" as it was a line
before where "b-z" means "b minus z"? This is completely illogical.

2) Does "inside (x-y)" mean "more than x and less than y" (>x && <y) or
"the same or more than x and the same or less than y" (>=x && <=y)?

There is no universal definition which says, that a number is only
inside an interval if it is more than the lower limit and less then the
upper limit.

But an expression like "a>x && b<y" is clear - a has to be more than x
and less then y where "a>=x && b<=y" includes the lower and upper limit.

3) What if x or y are not scalar values but expressions?

Let's say x is calculated as "p-t":

if (a inside(p-t-y)) {
  dosomething();
}

Well - of course this makes no sense. So you need to define a rule, that
expressions are either not allowed here or the have to be in paranthesis:

if (a inside((p-t)-y)) {
  dosomething();
}

But again: why is "p-t" an expresion "p minus t" and "(p-t)-y" means
"from p minus t to y"? This is also quite confusing.

If you go on like this, you may end up with a kind of natural language
parser and not a programming language.

And what exactly is your problem with "if (a>x && a<y)" ? The meaning is
completely clear.

JavaScript is *not* intended as "learning language". It is just a
scripting language, nothing else.

Either you take it it as it is or you create your own language where you
can implement all the things you want to have. Maybe this would be a
good exercise for you so you realize what it means to interpret source
code in a way that the computer knows what to do.

At least you should not suggest "-" for the interval parameter, so it
would be:

if (a inside(x,y))

But then you can also just create your own class for "a" which provides
an method inside():

if (a.inside(x,y))

Well you are quite correct it was indeed a good idea to have a local name for the indexed object, just careful to do it inside loop. Much easier to read now.

Do yourself and us a favour and create your own language which works
exactly how you want it. Then you don't have to complain all the time
how stupid ECMAScript ist.

It is:

Who is "you guys"? You have to ask the people maintaining ECMAScript.

Why are you being a total jerk again, posting over everything and undoing
anything I had done??  And then you ask why I call you names??

What are you talking about? Your posts are still there for everybody to
read. That's no reason to call me a "jerk".

It's even better for you: everbody can see, that you already mentioned
the URL at Mozilla a couple of days ago and that I seem have not to read
every other answer before I answer the original question.

So what? Are you an autist? Then I'm sorry to confuse you.

Yes, on Usenet you definitely should: it's called collaboration, indeed the
opposite of what you are doing, you cheap, hypocritical, abusive, liar.

So what??  And I am the autist?  Sure, keep going...

Let me guess... you will again continue to read my posts even after this
"plonk" and complain about your time getting wasted.

To help you a bit:

But alas - Google Groups doesn't have a killfile...
