Thank you. It's indeed a "tiny language", a foreign dialect of lambda-calculus made easy, a dwarf installed on top of shoulders of giants, the modern web browsers, taking benefit from the powerful web technologies they bring for free and from the huge eco-system at their fingertips. About scope, the point is that there is "no scope", functions are like combinators, isolated in a global context where everything is defined, constants, primitives and user defined functions.
