In order to code, we need compilers or interpreters.

These need to be running on our computers.

This might be a computer we are directly working on ...

or it might be a server we are accessing on the web.

This means:

1. You might already have compilers and interpreters running on your computer. In fact, it's almost certain.
2. You almost certainly have Javascript running. It's my understanding that's a quite capable language. Are there things it can't do? Maybe it can't write to or even access files on your hard drive, because it's designed not to raise any security questions.
3. What other compilers or interpreters might already be installed on your computer? Java? Could you write and run a Java application with your system as presently configured? How could you find out?

Then, you can also instal compilers or interpreters. Some of them are free.

1. Ruby.
2. PERL
3. CSS

The question is, once you install one of these, what can you do with it.

What is something very simple you can do with it, right from the start?

I'm going to explore that question in future posts.
