Hi, in previous class you told we can use double cotes within double cotes, but u used in this statement and it is working just fine!("This is header")
in the body section you can't call but the same section which mean inside the head section you can call or its accessible,if you want to call from body then declare as a globally i think .....
Alert is part of Javascript pop up, like it pops up in a box anytime you refresh your browser While document.write, puts it in your browser directly just like html
i am not under stand that. when you are writing a for loop than you are not declare the variable i. after that you are using to variable i directly, without declaring. and how to find the value of i out side the loop. it is local variable for loop.
