I am still a big fun of what made JS easy to use, develop, learn since born
... the ability to include a script in a HTML page and run it without being
forced of using different tools in the middle before results or even
requiring a web server at all.
I remember once I've read that scripting was cool 'cause no time wasted
compiling ... those days are gone in modern JS development.
