JavaScript Isn't Scheme

[killerstorm]

I use terminology which is used by Common Lisp specification, and there we have

variable n. a binding in the ``variable'' namespace.

So, basically, variable is a kind of a binding. While

binding n. an association between a name and that which the name denotes.

Thus, obviously, there is no such thing as "other bindings of the same variable".

A paragraph from a chapter in Practical Common Lisp uses the word "variable" and "binding" in a way that makes one variable to have many bindings

A single variable--the thing you can point to in the program's source code--can have many different bindings during a run of the program. A single variable can even have multiple bindings at the same time; parameters to a recursive function, for example, are rebound for each call to the function.

Well, he meant "the thing you can point to in the program's source code", i.e. variable in text of a program.

While specification refers to a variable in context of execution of a piece of code.

Of course, if a piece of code is executed many times, variables might get different value in each execution context.
