Javascript strings

[debby]

what are the values of thirdVar, fourthVar and fifthVar after these lines of javascript have been executed.

var firstVar = 'Joseph' ;
var secondVar = ' Locke' ;
var thirdVar = firstVar.charAt (0) + '. ' + secondVar;
var fourthVar = thirdVar.length;
var = 'The last character is' + thirdVar.charAt(fourthVar) + ' ! ' ;

isn’t that obvious? just do mentally, what the JavaScript engine does, it’s not complicated.

PS. aint that Ashley Lynx?

It will be empty space or null or undefined logically speaking. Because thirdVar.length will have 8. But the thirdVar is a string and it will be stored like [0] -> J, [1] -> ., [2] -> a space, [3] -> L, [4] -> o, [5] -> c, [6] -> k, [7] -> e. This is how the value will be stored. When u try to fetch charAt[8] it will return a empty value, null or exception.
