#124324 — Do not use var / what about import [Confusion by John Harris]

Attention to John Harris <niam@jghnorth.org.uk>
In case you are about to go on a fishing spree
for F.U.D. like here:

Fear, Uncertainty and Doubt
https://de.wikipedia.org/wiki/Fear,_Uncertainty_and_Doubt

Be warned, your findings might mostlikely come out
as lame accusations. Judging from your JavaScript
tutorials your are stuck somewhere in the yesterdays
yesterday of JavaScript, you write:

 > First, inside a function definition
 > var v;
 > makes v a local variable.
 > [...]
 > However, in 2015 two other kinds of variable
 > were introduced that do have block scope. They
 > are declared using the keywords const and
 > let instead of var.
https://www.jghnorth.org.uk/notes/JSfeats.html

Why not just admit that var is practically deprecated,
and make a fresher of your nonsene tutorials, remove it?
It's probably only still there for backward compatibility.

4 Reasons Why ‘var’ is Considered Obsolete in Modern JavaScript
https://plainenglish.io/blog/4-reasons-why-var-is-considered-obsolete-in-modern-javascript

Also I doubt you can run Dogelog Player for JavaScript
with your mindset, it requires ES6 modules.

Or try another hobby than JavaScript.
Like for example bird watching.

a) It was written back when this group's FAQ was still being updated.

b) It's job was to introduce JavaScript to novice programmers who knew 
nothing about the language.

c) It's aged much better than the FAQ as it concentrates on fundamentals 
rather than current practice.

There's nothing stopping you writing a replacement document.

Something else that is outdated. Why go into
the pain of making you own website? Start writing
blogs and use forums like for example:

https://medium.com/

https://qiita.com/

Time to invest: a) Time to register at the blog
service site plus b) Time to learn their markup language.
a) Takes usually 1 minute and b) takes around 5 minutes.

Write a blog about how you, John Harris, sees the
future of Garbage Collection and Datastructures, or
any other topic of your choice, I hope the topic

is not how to burp in a pub, by misunderstanding the
Drinkers Paradox. PyPy recently fixed a 10 years
old bug releated to their garbage collection:

Or another topic of choice could be to make
some testing across Prolog systems, like
Dogelog Player, Trealla Prolog, Scryer Prolog

who knows what Prolog system. Scryer Prolog
is an especially curious Prolog system, it
even doesn't have garbage collection at all,

and you can let it crash by filling the memory
with garbage. I guess they don't know how
to read a paper, like for example this paper:

[3] Carlson, M. et al. (1988): Garbage collection for Prolog based on 
WAM. Communications of the ACM 31, 6, 719–740, June 1988
http://dl.acm.org/doi/10.1145/62959.62968

Which even has nice pictures, that help you
understand the issues and algorithmic suggestions.

I guess John Harris mind will soon explode.
There is more isomorphism on the horizon:

pg-mem is an experimental in-memory
emulation of a postgres database. It
works both in Node or in the browser.
https://www.npmjs.com/package/pg-mem

Poor John Harris, give this man some valium
and an ice pack so that he can cool down.
