A re-introduction to JavaScript

Why a re-introduction? Because JavaScript has a reasonable claim to being the world’s most misunderstood programming language.

It is designed to run as a scripting language in a host environment, and it is up to the host environment to provide mechanisms for communicating with the outside world.

Great to look back on posts like this and see just how prevalent JavaScript has become.
