hi guys,
this is regarding the note thats written on page number 367 HFSJ.here it goes :-



of all the implicit objects,only pageContext is not a map.it's an actual reference to the pageContext object.

so whats the differnce between an actual reference and a map object

kindly clear my doubt

thanks in anticipation

map is map of key/value pair. it's sure difference from actual object.
