Synopsis
function.caller
Description
In early versions of JavaScript, the caller property of a Function object is a
reference to the function that invoked the current one. If the
function is invoked from the top level of a JavaScript program,
caller is null. This property may be used only from
within the function (i.e., the caller property is only defined for a
function while that function is executing).
Function.caller is not part
of the ECMAScript standard and is not required in conforming
implementations. It should not be used.
