Javascript: global object

The global object is created before control enters any execution context.

The global object has neither the [[Construct]] nor the [[Call]] internal method. Thus it cannot be used as a constructor with the new operator or be invoked as a function.

It has, however, the [[Prototype]] internal slot. This value is implementation-dependent.

escape(…)

eval(…) dynamically evaluates a string as JavaScript expression or statement.
