J tutorial
Here I shall talk about a powerful calculator called J. In fact,
it is so powerful that we should better not call it a
calculator. It is indeed a powerful general purpose programming language. But it is so
concise that it looks more like a calculator than a programming
language.
J is a language available for all major platforms, including
android and raspberry. Indeed, when I looked for a language that
will allow me to program in my android phone (make 2d, 3d plots,
doing math, processing images etc), J won the race over
Python (at least for me).
J is a scripting language. Interpreted. Just like R or
Python. But it is much easier to use once you get the hang of
it. I have been using R for years, and J for a few
months. Already I prefer to use J for many scripting problems.
A J program, I must admit, looks like gibberish to anybody new to
the language. A Python program will convey some meaning to a C
programmer unfamiliar with Python, but J is so very different
from the popular languages out there, that you might be
discouraged to use J at first.
