Rodney GreenfieldA "closure" is an expression (typically a function) that can have free variables together with an environment that binds those variables (that "closes" the expression).

A closure is formed when one of those inner functions is made accessible outside of the function in which it was contained, so that it may be executed after the outer function has returned. At which point it still has access to the local variables, parameters and inner function declarations of its outer function

Mr. DiGiA "closure" is an expression (typically a function) that can have free variables together with an environment that binds those variables (that "closes" the expression).
-
Closures are one of the most powerful features of ECMAScript (javascript) but they cannot be property exploited without understanding them
-
Function objects created with the
Functionconstructor always have a[[scope]]property referring to a scope chain that only contains the global object.Function objects created with function declarations or function expressions have the scope chain of the execution context in which they are created assigned to their internal
[[scope]]property.

The simple explanation of a Closure is that ECMAScript allows inner functions; function definitions and function expressions that are inside the function bodes of other functions. And that those inner functions are allowed access to all of the local variables, parameters and declared inner functions within their outer function(s).
