In type theory and programming languages, a type variable is a mathematical variable ranging over types. Even in programming languages that allow mutable variables, a type variable remains an abstraction, in the sense that it does not correspond to some memory locations. Programming languages that support parametric polymorphism make use of universally quantified type variables. Languages that support existential types make use of existentially quantified type variables. For example, the following OCaml code defines a polymorphic identity function that has a universally quantified type, which is printed by the interpreter on the second line: # let id x = x;;val id : 'a -> 'a =

Flexibility is fun, but use it with care (JavaScript is dynamically typed)
When you begin programming in JavaScript, you'll need to use variables. A variable is just a bit of storage to hold a value. Just about every line of code you write will use a variable of one kind or another, so it's a good idea to get familiar with the kinds of things you can put in varia
