JS FUNdamentals

If it's not fun, it's not JavaScript.

Expressiveness

Programming languages like BASIC, Python, C has boring machine-like nature which requires developers to write extra code that's not directly related to the solution itself. Think about line numbers in BASIC or interfaces, classes and patterns in Java.

On the other hand JavaScript inherits the best traits of pure mathematics, LISP, C# which lead to a great deal of expressiveness (and fun!).
