  • If a value is assigned
    and the actual object does not have a property with the corresponding
    name a property of that name is created and the value is assigned to
    it. If it has the property then its value is re-set.
  • all objects may have prototypes, and prototypes are objects so they, in
    turn, may have prototypes, which may have prototypes, and so on forming
    what is called the prototype chain. The prototype chain ends when one
    of the objects in the chain has a null prototype. The default prototype for the
    Object constructor has a null prototype so

  • • When a javascript function is called it enters an execution context,
      if another function is called (or the same function recursively) a new
      execution context is created and execution enters that context for the
      duration of the function call. Returning to the original execution
      context when that called function returns. Thus running javascript code
      forms a stack of execution contexts
    • First, in the execution context of a function, an
      "Activation" object is created.
    • The next step in the creation of the execution context for a function
      call is the creation of an arguments object, which is an
      array-like object with integer indexed members corresponding with the
      arguments passed to the function call, in order.
    • Next the execution context is assigned a scope. A scope consists of a
      list (or chain) of objects.
    • the Activation object is used as the Variable object (note this, it is
      important: they are the same object). Named properties of the Variable
      object are created for each of the function's formal parameters, and if
      arguments to the function call correspond with those parameters the
      values of those arguments are assigned to the properties (otherwise the
      assigned value is undefined)
    • It is the fact that the Activation object, with its
      arguments property, and the Variable object, with named
      properties corresponding with function local variables, are the same
      object, that allows the identifier arguments to be treated
      as if it was a function local variable.

  • 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).
  • 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). 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. Those local variables, parameter
    and function declarations (initially) have the values that they had
    when the outer function returned and may be interacted with by the
    inner function.
