Joy of this, Joy of that

I want to complement these joy posts by my feelings
about junk languages. My programming experience
includes a wide variety from machine language, assembly
language, Fortran, and C going back to the 60's.

I call Perl, Python, and Javascript junk languages:
because programs written in these are unstable. Some
modification in these can cause a perfectly functional
program to stop working because of some change that
was not backward compatible.

I ran into this problem way back in the 70's when I
was running Fortran programs on CDC machines. One
day my Fortran programs would no longer compile because
CDC had updated their compiler. I had no recourse
other than tracking down every "error" and programming
around that. Do that with a program that ran to
20 boxes of cards.

Although Perl supposedly had an automatic method
for updating my Perl programs, it didn't work
for me and I just abandoned all the stuff that
I had written up to that time.

I am now running into these same problems with
javascript programs using jsdom. Junk.
